Astaxanthin supplementation ameliorates simulated heat stress by regulating physio-biochemical responses in Sirohi goats.

The present study was undertaken to assess the ameliorative effect of dietary supplementation of astaxanthin in Sirohi goats under simulated heat stress conditions. Eighteen healthy female Sirohi goats were divided equally into three groups (n = 6): Heat-Stressed Control (HSC), Treatment 1 (T1), and Treatment 2 (T2). During the experiment, goats in the T1 group were supplemented with astaxanthin at the rate of 25mg/animal/day, while those in the T2 group received supplementation of 50mg/animal/day. The experiment was conducted for 42 days: 14 days of acclimatization period, next 21 days animals were exposed to 42ºC for 6h from 09:00h to 15:00h and 7 days of recovery period. On a daily basis, we recorded the physiological responses of goats and collected environmental data at the experimental site. Blood samples were collected 0 and 14th days of acclimatization, on 1st, 6th, 11th, 16th and 21st day of heat exposure and on the 7th day of the recovery period. The rectal temperature and respiration rates of the treatment groups were lower than those of the HSC group during the exposure period. Heat stress in the supplemented groups was associated with reduced levels of hepatic enzymes such as AST and ALT. Serum urea, creatinine and albumin levels were significantly (P < 0.05) different between control and treatment groups. It was thus concluded that dietary inclusion of antioxidant astaxanthin can ameliorate induced thermal load as evident from changes in physio-biochemical parameters in the Sirohi goats, that was more prominent at 50mg/ animal/day than 25mg/ animal/day.

Ovarian expression analysis of fecundity candidate genes in Goat breeds differing in prolificacy

To understand the genetics of goat fertility, goat breeds differing in prolificacy were used for exploring candidate genes using quantitative polymerase chain reaction. Ovaries (both left and right) of Black Bengal, Osmanabadi and Sirohi goats (n=3 from each breed) were collected from the local abattoir located in their respective breeding tracts. The RNA isolated from antral follicles was converted into cDNA. The β-Actin (ACTB) was used as a reference gene for quantifying the expression of BMP15, GDF9, BMPR1B, KISS1 and GPR54 mRNAs in ovaries. The results showed that BMPR1B, GDF9 and BMP15 genes were highly expressed whereas KISS1 and GPR54 were slightly expressed in the ovaries. Significant differences (P<0.05) were recorded in the gene expression of GDF9 and BMP15. Expression of these two genes varied in prolificacy being highest in Black Bengal followed by Osmanabadi and least in Sirohi. BMPR1B expression did not vary significantly among the goat breeds. In conclusion, the study provides baseline data and contributes toward the understanding of the molecular basis of prolificacy in goat breeds.

Comparative study on the expression profile of Aquaporin5 (AQP5) gene in skinfibroblast cells of native goats enabling their water utilization efficiency

Lack of availability of good quality and quantity of water affects the physiology of goats. Goats may adapt to thrive well in water deficit areas by making alterations in the expressions of aquaporin (AQP) genes for their efficient water use. The present study was carried out in skin fibroblast cells of Barbari and Sirohi goats. Under in vitro conditions, during different temperatures and osmotic treatments, variations in relative expression of AQP3 genes were observed. At higher temperatures the relative expression of AQP3 genes in Sirohi breed was found to be significantly higher (p&lt;0.01) than Barbari breed. However, during hyperosmotic concentrations at normal temperatures the relative expression of AQP3 mRNA was significantly ((p&lt;0.05) increased in both the breeds. During a high temperature combination with hyperosmotic concentration in cell culture of skin fibroblast cell the relative expression of AQP3 mRNA was increased in Sirohi breed (p&lt;0.01) whereas it decreased in Barbari goat’s breed. The variations in AQP3 gene expression during water stress condition and during hyperosmotic concentrations of skin fibroblasts cell culture suggests the positive involvement of AQP3 gene in maintaining the water balance in the body.

Goatary: A Gateway of Victory for Resource Deprived Farmers

Within animal husbandry, goat farming plays an essential role in livelihood security and economic sustenance of rural people by providing regular employment and income generation throughout the year. Also, it providing security against risk in agriculture. The present study was conducted to the empowerment of schedule cast farmers through goat husbandry as an economic Venture for low-income families of faster body weight gain and higher milk-producing goat breed “Sirohi” under ICAR, New-Delhi sponsored SC-SP project for “Entrepreneurship and to strengthen their livelihood and economic improvement of Schedule cast youth” in the year 2019-2020, in Jodhpur district of western Rajasthan. Ten Sirohi goat units were demonstrated to each identified schedule cast respondent. Each unit comprised of ten females and one buck. The results revealed that the improved Sirohi goat has an immense production potential in arid regions under a traditional low input production system. The average expenditure and income on the rearing of animals were calculated at ` 26,576 and ` 60,174, respectively. The benefit-cost ratio was recorded at 1:2.26, which appears to be very much economical and viable. It is a profitable and economic venture for resource-poor families in livelihood and entrepreneurship

Performance of different breeds of goats under semi-intensive system in eastern Himalayas

A study was conducted to compare the performance of Sirohi and Jakhrana goats and their adaptability compared to native Assam Hill goats in eastern Himalayas. The overall least squares means for body weights at birth, 3, 6, 9 and 12 months of age were 2.53±0.03, 9.25±0.42, 16.35±0.14, 19.73±0.42 and 24.65±0.25 kg in Sirohi goats, 2.31±0.07, 8.23±0.35, 13.49±1.14, 17.52±0.66 and 22.89±0.87 kg in Jakhrana goats and 1.82±0.31, 6.78±0.28, 9.85±0.43, 12.61±0.62 and 15.85±0.23 kg in Assam Hill goats, respectively. The age at first kidding was significantly (p<0.05) lower in Assam Hill goats (417.00±0.03 days) than Sirohi (684.61±0.75 days) and Jakhrana (568.25±0.03 days) goats. Similarly, the kidding interval was significantly (p<0.05) shorter in Assam Hill (267.00±0.61 days) as compared to Sirohi (370.61±0.38 days) and Jakhrana (311.16±0.15 days) goats. The results indicated that Sirohi breed performed better in comparison to Jakhrana in eastern Himalaya in terms of body weight at different ages. However, Assam Hill goat being a native breed performed better than both the breeds in reproductive performance as evident by earlier age at first kidding, shorter kidding interval and higher twins and triplets.

Determination of best fitted regression model for assessment of live body weight from morphological traits in Sirohi goat in Udaipur

The objective of this research was to predict the live body weight from morphological traits of Sirohi goat. Based on data of Sirohi goat of different age (0–3 months, 3–6 months, 6–9 months and 9–12 months) kept under All India Co-ordinated Research Project on goats for Sirohi goats (AICRP) at Livestock Research Station, Bojunda, Vallabhnagar, and Dabok areas of Udaipur, Rajasthan during the year 2017. Simple and multiple regression models were used to explore the live weight and 5 morphological traits while taking animal’s age and sex into consideration. Correlation between body weight and morphological traits at different ages were positive and strongly correlated (P≤0.01). Simple and multiple regression models were fitted with body weight as the dependent variable and morphological traits as independent variables. The coefficient of determination in different equations indicates that combination of heart girth, height at withers, body length, punch girth and rump height succeed in estimating body weight better than single morphological trait. It can be concluded that the best fitted multiple regression models including heart girth, height at wither, punch girth, body length and rump height may be considered best for prediction of body weight of Sirohi goat.

Genetic study on growth efficiency in Sirohi goats under field condition

A study was conducted to estimate the pre- and post-weaning growth efficiency (GE) in 6748 Sirohi goats born during 2005 to 2017 under field conditions. The overall least-squares mean for pre-weaning (0-3M) and post-weaning (3-12M) growth efficiencies were 4.31±0.09 and 1.10±0.031 Kg per kg, respectively. Sire, type of birth, sex of kid and cluster had highly significant (P≤0.01) effect on both pre and post-weaning relative growth efficiencies whereas year of birth, season of birth and parity had highly significant effect (P≤0.01) only on pre-weaning growth efficiency. Heritability estimates for pre- and post-weaning growth efficiencies were 0.53±0.06 and 0.44±0.06, respectively. Genetic and phenotypic correlation between two traits was negative.

A comparative study on the expression profile of aquaporin 3(AQP3) gene in the skin fibroblast cells of Barbari and Sirohi breeds of goat

Lack of availability of good quality and quantity of water affects the physiology of goats. Goats may adapt to thrive well in water deficit areas by making alterations in the expression of aquaporin (AQP) genes for their efficient water use. The current study was carried out in skin fibroblast cells of Barbari and Sirohi goats. Under in vitro conditions, during different temperatures and osmotic treatments, variations in relative expression of AQP3 genes were observed. At higher temperatures the relative expression of AQP3 genes in Sirohi breed was found to be significantly higher (p<0.01) than Barbari breed. However, during hyperosmotic concentration at normal temperatures the relative expression of AQP3 mRNA was significantly ((p<0.05) increased in both the breeds. During a high temperature combination with hyperosmotic concentration in cell culture of skin fibroblast cells the relative expression of AQP3 mRNA was increased in Sirohi breed (p<0.01) whereas it decreased in Barbari goat’s breed. The variations in AQP3 gene expression during water stress condition and during hyperosmotic concentrations of skin fibroblasts cell culture suggests the positive involvement of AQP3 gene in maintaining the water balance in the body.

A Study on Growth Performance of Weaned Kids of Sirohi Goat Fed with Different Levels of Concentrates

The present investigation was conducted a study on growth performance of weaned kids of Sirohi goat fed with different levels of concentrates for the effect of concentrate feeding on body weight gain. Twenty four kids of Sirohi breed between 3–4 months age were randomly selected on the basis of uniform body weight, age and divided into 3 groups of 8 kids each at the goat farm of S.K.N. College of Agriculture, Jobner. Group T1 served as control supplemented with 50 g concentrate per kid per day for 3 months. Group T2 (treatment) supplemented with 50, 100 and 150 g concentrate and T3 (treatment) with 100, 150 and 200 g concentrate per head per day for 1st, 2nd and 3rd month, respectively. Other management practices were similar for each group. Fodder of khejri loom was offered ad-libitum to all groups. Body weight of kids was recorded weekly. Group T3 fed with more quantity of concentrate achieved the highest (85.77 g/day) average weekly weight gain followed by T2 (69.22 g/day) and control group T1 (61.33 g/day). Maximum average total weight gain per kid was observed in group T3 (7.72 kg) followed by T2 (6.23 kg) and least was found in T1 (5.52 kg). Thus, from above findings it can be concluded that T2 and T3 treatments showed significantly improved growth performance in Sirohi kids and higher level (T3) was relatively the best level in terms of both biological and economical returns.

Significance of environmental factors that influence on fortnightly test days milk yield of Sirohi goat

The data of 22,630 fortnightly test day milk yield of 2,263 Sirohi does at different lactations were used and subjected to least square analysis to study the effect of various non-genetic factors like cluster, periods of kidding, season of kidding, parity, type of birth and regression of dam’s weight. The overall least-squares means of different individual fortnightly test day milk yields increase from 0.820±0.04 kg on TD1 (15th day of lactation) to a peak yield of 1.070±0.06 kg on TD2 (30th day of lactation) and subsequently declined to 0.348±0.01 kg on TD10 (150th day of lactation). Cluster and period wise variation were highly significant on all stages of fortnightly test day milk yields. The significantly higher test day milk yield were observed in winter kidded does as compared to summer and rainy kidded, it could be milk climatic conditions. The parity had statistically highly significant effect on fortnightly test day milk yields, in which seemed that milk yields increase as parity increase, thereafter declined slowly. The effect of type of kidding was non-significant on overall fortnightly test day milk yield under this study. The regression of dam’s weight at kidding was positive and highly significant (P≤ 0.01) on all fortnightly test day milk yield. In order to increase goat milk production, goat keepers need to be focused on nutritional and others environmental conditions as it affect their flock.
