Solar irrigation system: Analysis of the solution for livestock production in North Cameroon

This article examines the impact of implementing a solar irrigation system on livestock production in North Cameroon, a region marked by climatic challenges and increasingly dry conditions with 600 to 1,200 mm of rainfall per year and temperatures between 30°C and 40°C. Livestock farmers in the region rely heavily on natural pastures and forage crops to feed their livestock, but these resources are insufficient during periods of drought. The area is home to around 2 million head of cattle, with an estimated 500,000 to 700,000 head of sheep and 300,000 to 500,000 head of goats. Our methodology involved a comparative before-and-after analysis, where data on crop yields, pasture quality and animal performance were collected. Statistical simulation was used to assess improvements in pasture biomass, forage yield and animal performance. The results show significant improvements if the solar irrigation system is installed, with: a 30% increase in biomass; a 50% increase in forage yield with a 16.7% gain in animal weight; a 20% increase in milk production; a 30% reduction in forage procurement costs; and a 33.3% increase in income generated. These results indicate that solar irrigation will have a positive impact on farm productivity and profitability. The installation of a solar irrigation system in Northern Cameroon represents a sustainable and economically viable solution for improving livestock production in a region vulnerable to drought.In sub-Saharan Africa, solar irrigation systems have been successfully implemented in several countries, including Kenya, Ethiopia, Mali and Burkina Faso. These projects have demonstrated the viability of this technology in semi-arid and arid environments, with notable improvements in agricultural production and water management. The climatic and geographical conditions in Northern Cameroon are similar to those in the regions where solar irrigation systems have been tested.

The Tendency of Livestock Growth in Ethiopia: A Review

Ethiopia ranks first in Africa and 5th in the globe in its livestock population. The livestock subsector is immensely contributing about 60-70 % to the population’s livelihood and about 80% of the farmers use animal traction to plough their croplands. This study involved gathering livestock-based data from the Central Statistical Agency (CSA) for the years 2004/05 to 2018/19. Additionally, information on livestock holders was systematically organized and analyzed to track progress over the years. Quantifiable values indicating increases were presented in tables and figures. The relationship between cattle numbers and livestock owners’ growth trends was tested using the Pearson correlation. The findings were further supported or challenged through a comprehensive literature review. The data show that the cattle population grew by 57% in 2018/19 than the number it was at the end of 2004/05 and the number of cattle owners increased by about 53 %. Likewise, the total number of sheep population grew by 82.69 % and their holders by 53%, the total goat heads grew by 162.2% and the camel population by 284%. From the total stock of cattle, 97.92% and 99.72% of sheep and all the goats and camels were identified as indigenous, respectively. The study found a significant and strong correlation (p less than 0.01) between the number of animals used for production and the number of holders. This suggests that the growth in livestock population is primarily due to an increased number of livestock owners, rather than an increase in the number of animals per holder. The work identifies bottlenecks in livestock development and provides insights into growth trends and underlying causes. It highlights opportunities for policy interventions to enhance sustainable livestock production. Further research is recommended on addressing feed and water shortages and evaluating policy and institutional setup effectiveness.

Investigation of Some Environmental Factors on Reproductive Characteristics, Milk Traits and Kleiber Ratios of Kilis Goats Reared in the Fertile Crescent of Türkiye

This study was carried out to determine the effect of environmental factors on some yield traits in Kilis goats. For this purpose, 6000 heads of Kilis goats each year, and a total of 30000 goats and kids born from them for 5 years, were the subject of the research. Milk control in goats was calculated by the ICAR-AT method. At the end of the study, Average birth weight was 3.56 kg, weaning weight was 15.06 kg and daily live weight gain was 191.64 g in kids. KR value found to be 23.6±0.03 in kids. Lactation milk yield in mothers was determined as 367.64 kg. As a result, it was determined that environmental factors were effective on the reproductive parameters and milk yield characteristics of Kilis goats and the developmental characteristics of kids. The crucial determination of these factors in the breeding of this breed will increase the accuracy of selection. In addition, the success will also be increased by starting the transition from the traditional breeding approach to the genomic breeding method and by combining these two strategies.

Relationships of infrared thermography temperature with core temperature in goat.

Rectal temperature is widely used as an indicator of animal health. However, rectal temperature is conventionally measured by an invasive method, which may reduce animal welfare. So, this study aimed to determine the relationships between the deep-body (core) temperature and body surface temperatures in goats and develop a linear regression equation to establish the core temperature based on body surface temperatures. Body surface temperatures (head, eye, muzzle, horn, back, scrotum and groin) of goats were measured by infrared thermography (IRT). Ambient temperatures were measured by digital thermometer. Core temperatures were measured by a digital vet thermometer. Pearson correlation analysis was used to analyze the relationship between body surface temperatures, ambient temperature, and core temperature. Simple linear regression analysis was used to develop core temperature assessment equations. Correlation analysis showed that groin temperature was highly correlated with core temperature, and low correlated with ambient temperature. The body surface temperature of other region was low correlated with core temperature, and highly correlated with ambient temperature. Regression analysis showed that the determination coefficient of core temperature assessment equation based on groin temperature was the highest (P < 0.0001, R2 = 0.55), and those based on surface temperature of other regions were low (P < 0.01, R2 ≤ 0.16). We concluded that body surface temperatures obtained by IRT could be used for the assessment of goat core temperature. The core temperature assessment equations developed by the temperature of the body surface, which is less affected by ambient temperature, was found to have a higher determination coefficient than the equations developed using body surface temperature that is more affected by ambient temperature.

Morphometric and Phenotypic Characterization of Pote Goats in Soket Laok Village, Tragah District, Bangkalan Regency, Madura

The purpose of this study was to analyze the morphometric characteristics of Pote goats in Soket Laok Village, Madura Island. The material used was 200 Pote goats with an age range from over 1 year (PI0&gt;6) to more than 3.5 years (PI8). The sample included 90 goats aged over 1 year (PI0&gt;6), 36 goats aged between 1 and 1.5 years (PI2), 54 goats aged between 1.5 and 2.5 years (PI4), 16 goats aged between 2.5 and 3.5 years (PI6), and 4 goats aged over 3.5 years (PI8). The method used is a survey method which includes conducting surveys and interviews. Data were obtained using a purposive sampling technique. The results showed that morphometric measurements on the head and body of Pote goats had the highest average at PI 8, which means that along with the increasing age of Pote goats, it will affect the body size of goats. The results of the dominant phenotypic characteristics of Pote goats are the shape of a pitcher udder, the shape of long drooping ears, the shape of flat horns, rectangular pupils, convex facial profiles, there is rewos hair both in males and females and there is no beard, and phenotypic Pote goats with different ages do not have significant differences.

The Choice of Breeding Objectives and Selection Criteria Decided by Breeders of Various Goat Breeds and Factors Influencing Them

Knowledge of breeding objectives and selection criteria is essential for a successful breeding program, a questionnaire was prepared, and distributed among breeders of various goat breeds in Abu-Dhabi Emirate to explore their breeding objectives and selection criteria of various goat breeds that they raise. A total of 293 different goat herds with a total of 49911 heads of goats were investigated. A stepwise logistic regression was applied using LOGIST procedure of SAS. The results suggest that goat breeders in UAE are breeding goats mainly for meat production (94%), adaptability to environment (40%), and disease resistance (35%). Only few breeders considered milk production (21%) as breeding objective. Factors influenced breeders’ decision on breeding objectives were breed of goat, region, property type, and herd size. Nine out of the twelve doe selection criteria chosen by goat breeders are considered objective selection criteria and only three are subjective selection criteria. Growth rate, fertility, twining ability and body morphology selection criteria were considered the most important on the average by Emirati goat breeders with a medium proportion (60–65%). Goat breeders have put slightly more pressure on buck subjective criteria. The most important buck selection criteria were growth rate (80%) and body morphology selection criterion (76%) then fertility, buck being one of twins and breed purity with averages in 50-55%. Although; increasing meat production was the main breeding objective, an effective breeding program must incorporate different selection criteria for does and bucks considering differences in breeds, regions, property types and herd sizes.

Prediction of body weight using body measurements in some sheep and goats in Qatar

ABSTRACT The study aimed to identify the relationship between body measurements and the weight of sheep and goats. A total of 324 heads of sheep and 261 heads of goats were used. Measuring of body weight (BWt) and body measurements as heart girth (HG), height at wither (HW) and body length (BL) were taken on both types of animals for 3 successive months. Correlations between body weight and measurements were tested. Linear and non-linear regressions of body weight on the most correlated body measurements were calculated. HG, HW and BL were significantly related to BWt. HG had the largest correlation coefficient. Power regression had the highest coefficient of determination (R2 = 0.91) and lowest error of estimate (SE = 7.42). The power regression model (BWt = 0.0006*HG2.5608) was tested against the actual weight of another animal’s population of 119 heads of goats and 171 heads of sheep using paired t-test analysis. No significant variation was observed between the actual and estimated body weights. The model overestimated weight by 1.5%. It was concluded that body weight could be estimated with a high accuracy using the corrected model BWt (kg) = (0.0006*(HG2.5608))–(1.5*(0.0006*(HG2.5608)/100)).

Limited forage for livestock during the dry season has an impact on low livestock productivity, so a source of feed other than grass is needed as an effort to utilize local resources.The purpose of research is voluntary feed intake level and organik matter digestibility adult female goat given by 3 different feed. It was carried out on experimental farm of Hasanuddin University for 3 months. A total of six a head of adult male goats aged around 1.5 years with preliminary weights 11-15 kg were used and place at individual pen of 100 x 50 x 100 cm with 80 cm above ground level. This research was designed using RBSL with 3 treatments and it was used 2 heads of goat replication. The feed treatment covered 3 kinds of leaves, namely mango (R1), jackfruit (R2), and banana (R3). The voluntary feed intake (kg/day) was measured based on difference between given and remained feed weights. The measurement of feed digestibility (%) using Total Collecting Method, covering total of feed comsumption and total of goat faeces (24 hours) separeted with urine. The research result showed that the voluntary feed intake level R1 leaves was heigher than R2 and R3 leaves, whereas the level of crude fiber digestibility and crude fat of R1 higher than R2 and R3, but digestibility of crude protein R3 higher than R1 dan R2.

Towards understanding the type and function of indigenous goats: input for genetic improvement and conservation programme

ABSTRACT This study aimed to provide a better understanding of the type, function, and production potential of Central Highland goats. Morphometric measurements were collected from 510 heads of goats. About 17 biologically important structural indices were computed using morphological trait measurements. The data were analyzed using SAS’s general linear model, principal component analysis, and stepwise multiple regression techniques. Body index value indicate that the Central Highland goat’s shape is rectangular, which is good conformation for meat production. The dactyl thorax, transverse pelvic, longitudinal pelvic, relative depth of thorax, and width indices suggest their suitability for meat production. However, proportionality and length indices showed an aptitude for milk production. Besides, the body ratio and depth indices indicate less susceptibility of this goat breed to dust infestation and arthritis, good walking ability, good foraging capability, and move easily in sloppy areas. In conclusion, structural indices showed that Central Highland goats could be classified as having a dual purpose and better aptitude for meat production. The results of this study could be an input for designing genetic improvement and conservation programmes for the sustainable utilization of indigenous goats.

Comparison non-linear growth models to reflect body weight and body measurements of pre-weaning Kejobong goat

This study aimed to compare two growth models that reflect body weight and body measurement of pre-weaning Kejobong goat. A total data records of 35 heads of Kejobong goat observed for 14 weeks in five variables were used in this study. Two non-linear growth models (Gompertz and Logistic model) were applied for analysis of growth to compare growth performance by Non-Linear Mixed Model. Result showed Gompertz models has smaller AIC, BIC and σ2e value than those Logistic models. The growth curve models based on Gompertz were: y = 23.94 exp (-1.43 exp−0.01764*age) for body weight; y = 61.72 exp (-0.5 exp–0.01805*age) for wither weight; y = 13.12 exp (-0.35 exp−0.026*age) for chest width; y = 55.72 exp (-0.50 exp −0.01805*age) for hip height and y = 52.30 exp (-0.50 exp-0.01805*age) for hearth girth. It conclude that Based AIC, BIC and σ2e value, Gompertz model is the most fitted growth model for reflecting body weight and body measurement of pre-weaning Kejobong goat than those Logistic model.

Resin cast in situ: A technique to demonstrate the vasculature of the Nervous system: In Goat Model

Background: As Anatomical education advances very rapidly, and at the same time, there is huge demand and scarcity of true biological models, mainly brain tissue. In this scenario, in 1977, Guther Von Hagens worked on plastics and experimented voraciously on diffusing various plastics into large specimens and ultimately succeeded and coined the term “Plastination”. This technique is very popular in Western countries as the latter greatly minimizes the health hazards due to formalin exposure while dealing with biological tissue. In continuation with the advancement of expensive plastination to cost-effective resin casting, especially studies over the complex structures like the brain and spinal cord. In This study, we emphasize the cost-effective Resin cast-in-situ method to demonstrate the vasculature of the brain and spinal cord. Materials and Methods: After obtaining the prior permission, we collected the Five (5) Goat heads from the slaughterhouse. Following the standard dissection procedure over the neck region, identified and canulated the major neck vessels. Through the vessels normal saline water, formalin, and pigmented resin were administered and preserved the goat head using routine preservation technique. After 36 to 48 hours, the routine dissection was scheduled to expose the brain and upper spinal cord segments, and finding were captured and recorded. Results and Discussion: The specimens show good penetration of dye in the artery and veins, and it’s easy to appreciate and study the vasculature of the brain and upper spinal cord segments, including the Bastons plexus of veins. Conclusion: In comparison with regular silicon casting, resin casting is very cost-effective and long-lasting, with good penetration of the resin substance up to the capillary level. Furthermore, similar studies may be conducted using in combination with whole organ plastination using silicon and resin embedding. KEYWORDS: Resin cast in situ, Brain Vasculature, Plastination, Silicon Casting.

Measurement of Brain Strains in a Goat Head Under Impact Loading

Abstract Measurements of brain deformations under dynamic loading are required to understand the biomechanics of traumatic brain injury (TBI). In this work, we have experimentally measured two-dimensional (2D) brain deformations in a sacrificed goat brain under injurious impact loading. To facilitate imaging, the goat head was dissected along the longitudinal midline. Goat head response was studied for sagittal plane rotation. Full-field, 2D deformations in the midsagittal plane of a goat brain were obtained at spatiotemporal resolutions of ∼1 mm and 0.4 ms, respectively. Results elucidate the dynamic strain evolution. The goat brain underwent large deformation. The strain pattern was heterogeneous. Peak strains in various brain regions were established within ∼20 ms, followed by negligible strain development due to the considerable viscous dissipation. The Cerebellum region experienced the highest strain, followed by cortical and subcortical regions. Strain concentration in the goat brain near the stiff membrane of the tentorium was observed. The strains in a brain simulant of a head surrogate (obtained previously) were also compared against the goat brain response. A response in the brain simulant was comparable to the goat brain in terms of strain pattern, peak strains in various substructures, and strain concentration near the membrane. However, the brain simulant was less dissipative than the goat brain. These results enhance the current understanding of the biomechanics of the brain under dynamic loading.

Fasciolous invasion as a sanitary and hygienic threat to the population and animal husbandry in the subjects of the Caspian region of Russia

Introduction. WHO considers human fascioliasis to be a global epidemic threat of a parasitic nature.&#x0D; Materials and methods. The studies were carried out using methods of in vivo diagnostics used in medical and veterinary parasitology (the method of successive washings of feces; the Fülleborn method or the flotation-sedimentation method by Demidov) in relation to samples of feces and soils. In total, in six subjects of Russia to study the spread of fascioliasis in animals in the conditions of slaughterhouses, there were examine the liver in 1800 heads of slaughter sheep, 700 heads of goats, 1000 heads of cows and only 6000 soil samples for the detection of Fasciola hepatica eggs.&#x0D; In 2011–2019, medical services of 6 subjects of the Caspian region in 21 settlements carried out scatological diagnostics of the population aged 8 to 65 years, in the amount of 25 thousand people, to clarify the incidence of human fascioliasis. The results of the studies were statistically processed according to the method of N.A. Plokhinsky using the software Microsoft Excel 2008. The occurrence index – the percentage of individuals or eggs of F. hepatica in relation to the total number of examined objects – was based on monitoring and analysis of reports from regional divisions of the Federal Service &#x0D; for Supervision in Protection of the Rights of Consumer and Man Wellbeing (Rospotrebnadzor) and the Department of Veterinary Medicine of the Ministry of Agriculture of Russia for 2011–2019.&#x0D; Results. Coproovoscopy of 25 thousand samples of faeces for the presence of eggs of the pathogen of fascioliasis, taken from the population of 21 cities of the Caspian region of the Russian Federation, revealed their absence. The trend in the index of occurrence of goat fascioliasis in 2011–2019. had an annual growth trend of 0.03%; in sheep by 0.06%; in cattle by 0.05%, which also characterizes the lack of control measures.&#x0D; In 6 Republics of the Caspian region, the indices of occurrence and abundance of fascioliasis in goats, sheep and cows increased by 2–2.5 times, which indicates the threat of invasion to the development of livestock industries. Soil samples taken for research were contaminated with invasive elements of Fasciola hepatica in 100% of cases.&#x0D; Conclusion. The occurrence and abundance indices of F. hepatica eggs were found to be 0, which indicates epidemic well-being in relation to zoonosis. Research conducted indicate to the gain in the incidence index of fascioliasis in goats, sheep, and cows. The 100% contamination of the territories of rural pastures and remote mountain pastures with invasive elements of Fasciola hepatica is a biological and sanitary-hygienic threat to livestock and the population of the Caspian region of Russia.

Prevalence of Oestrus ovis in small ruminants from the eastern Iberian Peninsula. A long-term study.

Oestrus ovis is an obligate parasite that causes myiasis in domestic ruminants, being commonly found in the Mediterranean area. From 2009 to 2019 a total of 3476 heads of culling sheep and goats from the Mediterranean coast of Spain were examined for the presence of O. ovis. The total prevalence was 56.3%, significantly higher in sheep than in goats (61.2% and 43%, respectively). Differences were found in the mean annual prevalence, with the highest value being registered in 2018 (61.7%) and the lowest in 2012 (50.3%). Autumn, for sheep, and winter, for goats, were the seasons with the highest number of infested specimens. Temperature, but not rainfall, was found to be associated with prevalence (p < 0.05). Most L1 were found in the anatomic region I (septum, meatus, and ventral conchae), while L2 and L3 were mainly located in regions II (nasopharynx, ethmoid labyrinth, and dorsal conchae), and III (sinuses). The overall intensity was 12.8 larvae per head, significantly higher in sheep (13.3) than in goats (3.5). Our results confirm the high prevalence of O. ovis in sheep and goats in this geographic area over the last decade, with the trend increasing in recent years in association with higher mean temperatures.

A Comparison of Elevation, Perforation Rate, and Time Spent for the Crestal Sinus Elevation Intervened by Piezosurgery, CAS-Kit, and Osteotome in a Novel Goat Model.

This study aimed to compare the differences among Piezosurgery, CAS-kit, and Osteotome regarding safe elevation, perforation rate, and time spent and to observe and analyze different sinus lifting efficacy of the three methods. Twenty-one fresh goat heads (42 sinuses) were investigated. CBCT images confirmed the feasibility of the goat model. The maxillary sinus was successively lifted to 5, 7, and 9mm by Piezosurgery, CAS-kit, and Osteotome until the sinus membrane was perforated or lifted to 9mm. In the end, final elevation, sinus perforation, and time spent were recorded. Piezosurgery and CAS-kit lifted sinuses to relatively higher heights than did Osteotome (P = 0.000). Perforation rates (14.29, 21.43%) of the Piezosurgery and CAS-kit were far lower than that of the Osteotome (85.71%). In the Osteotome group, the time of lifting to 9mm was significantly shorter than that of Piezosurgery and CAS-kit (P = 0.000). There was no statistical difference in time spent between the latter two (P = 0.115). The lifting height of the Osteotome was limited, but it took the shortest time for sinus lifting. Piezosurgery and CAS-kit had higher lifting heights and lower perforation rates compared with Osteotome.

Questionable accuracy of CBCT in determining bone density: A comparative CBCT-CT in vitro study.

The accuracy of the estimation of radiological bone density with the use of the cone-beam computed tomography (CBCT) grayscale is still questionable. Standardization and correlation with the gold standard computed tomography (CT) Hounsfield units (HU) is required prior to clinical application. The objective of the present study was to evaluate the reliability of the grayscale for the estimation of bone density, using samples with intact soft tissue in order to substantiate the clinical use of the scale. A total of 240 sites in 20 goat heads were scanned to obtain radiological bone mineral density via Hounsfield units in CT and the grayscale in CBCT. The anatomical architecture of soft tissues was preserved for all samples. Two observers obtained the data, which consisted of 3 variables (mean, minimum and maximum) for both scales. The statistical analysis of the data was conducted using Cronbach's alpha, Pearson's correlation coefficients, the independent samples t tests, and regression analysis. Differences in the means of the mean, minimum and maximum values between the 2 scales were statistically highly significant (p = 0.000). The correlation coefficients for the mean, minimum and maximum values of the 2 scales were 0.496, 0.037 and 0.396, respectively. Regression analysis revealed that the R2 values for the mean, minimum and maximum values were 29.79%, 21.05% and 19.45%, respectively. The positive but weak correlation between the 2 scales and the low predictive reliability of the grayscale reveals its questionable applicability for the estimation of density in comparison with the standard HU.

An Integrated Goat Head Detection and Automatic Counting Method Based on Deep Learning.

Simple SummaryTo achieve precision and intelligence in farming, automatic recognition and counting of goats are important and fundamental parts of the process of large-scale goat farming. Currently, many farms with low modernization use manual counting, which has the obvious shortcomings of low efficiency and difficulty in avoiding duplication and omissions due to the large population base and frequent counting needs of goats. In order to solve this problem in the farming process, an efficient and accurate goat counting method is urgently needed. In this study, we address the above problem by constructing an integrated deep learning model for automatic detection and counting of goats based on computer vision technology with the Chengdu Ma goat as the research object. It is worth noting that we have improved the model using a series of advanced and effective strategies to enhance the performance of the model. Experiments show that our method can achieve accurate automatic counting of goats in a practical breeding environment. The method is beneficial to the regionalized management of goat barns and can be applied to different goat species with high practicality.Goat farming is one of the pillar industries for sustainable development of national economies in some countries and plays an active role in social and economic development. In order to realize the precision and intelligence of goat breeding, this paper describes an integrated goat detection and counting method based on deep learning. First, we constructed a new dataset of video images of goats for the object tracking task. Then, we took YOLOv5 as the baseline of the object detector and improved it using a series of advanced methods, including: using RandAugment to explore suitable data augmentation strategies in a real goat barn environment, using AF-FPN to improve the network’s ability to represent multi-scale objects, and using the Dynamic Head framework to unify the attention mechanism with the detector’s heads to improve its performance. The improved detector achieved 92.19% mAP, a significant improvement compared to the 84.26% mAP of the original YOLOv5. In addition, we also input the information obtained by the detector into DeepSORT for goat tracking and counting. The average overlap rate of our proposed method is 89.69%, which is significantly higher than the 82.78% of the original combination of YOLOv5 and DeepSORT. In order to avoid double counting as much as possible, goats were counted using the single-line counting based on the results of goat head tracking, which can support practical applications.

Incidence of Sinus Membrane Perforation Using Two Types of Implant Drills: An Ex Vivo Animal Study.

This ex vivo study evaluates the incidence of sinus membrane perforation during implant site osteotomy with two different types of drills and drilling techniques. Fifty goat heads with 50 sinus pairs (100 sinus sides) were assigned to two groups (osseodensification bur [OB] group and inverse conical shape bur [ICSB] group) to simulate transcrestal sinus elevation (50 sinus sides per group). An osteotomy was performed to pass through the lateral sinus wall no more than 3 mm. The integrity of the sinus membranes was examined and confirmed under a microscope. Of the 50 sinuses per group, the OB group presented with 14 (28%) perforated sinuses, while the ICSB group presented with 2 (4%) perforated sinuses. Of the 14 perforations from the OB group, 6 (42.9%) showed a pinpoint perforation pattern, 4 (28.5%) of which were not visible until direct air pressure was applied. Overall, the ICSB drill group demonstrated a lower sinus perforation rate than the OB group.

Dry Matter Intake and Digestibility of Napier and Treated Rice Straw Diet in Goats

Plant by-products such as rice straw can be utilized to optimize ruminant feed resources and productivity. This study aimed to determine the intake and digestibility of the basal diet (Napier grass) and treated rice straw diet in goats. A total of 16 heads of male and female Philippine native goats were used in the study. Experimental animals were arranged in randomized complete block design with four treatments and four blocks – weight and sex were used as bases for blocking. The treatments were the following: Treatment 1 (T1): 60% Napier grass + 40% untreated rice straw (control); T2: 60% Napier grass + 40% urea-treated rice straw; T3: 60% Napier grass + 40% fish amino acid (FAA)-treated rice straw; and T4: 60% Napier grass + 40% fermented plant juice (FPJ)-treated rice straw. The gathered data were dry matter intake (DMI), DMI as percent body weight (% BW), total and percent dry matter digestibility (% DMD), rumen pH and weight gain. All data were analyzed using the analysis of variance for RCBD. Comparisons of treatment means were determined using the least significance difference test. The results showed that DMI and DMI as % BW were significantly (p &lt; 0.05) affected by the treatments. Furthermore, total DMD and % DMD were significant (p &lt; 0.05). FPJ treatment gave the highest DMI for rice straw. Moreover, goats fed with rice straw treated with urea, FPJ and FAA efficiently digested the diet compared with the control treatment.
