This study was carried out to determine the nutritional value of coconut pulp (Cocos nucifera l.) with different fermentation times using Aspergillus niger as a poultry feed ingredient. The work was conducted at the Laboratory of the Faculty of Agriculture, Musi Rawas University, from January to April 2019 and proximate analysis was carried out at the Nutrition Laboratory of the Faculty of Animal Science, Jambi University. The study used a completely randomized design (CRD) with 6 treatments during fermentation (1, 2, 3, 4, 5 and 6 days of fermentation with codes L1, L2, L3, L4, L5 and L6. The observed variables were dry matter (DM), crude protein (CP), crude fiber (CF), and crude fat (CFat). The results show that 6 days of fermentation reduced BK and increased CP in fermented coconut pulp to 90.71% and 7.41%. The L5 treatment reduced SCF and CFat content to 8.75% and 11.21%. The best fermentation time of coconut pulp with Aspergillus niger was on day 6.

Quail eggs are one of the food sources of protein derived from quail, and are widely chosen for consumption by Indonesian people besides chicken eggs. This research aimed to determine the ability of black cumin and noni leaf to improve the quality of egg quail. The material used for this research was 66-day-old Autumn strain quail, as many as 96 heads, 6 each for each experimental unit. The research method used a completely randomized design (CRD) which consists of 4 treatments and 4 replications that were P0 (basal feed), P1 (basal feed + 1% black cumin flour + 3% noni leaf flour), P2 (basal feed + 2% black cumin flour + 2% noni leaf flour), P3 (basal feed + 3% black cumin flour + 1% noni leaf flour). Analysis of variance shows that the treatment did not have a significant effect (P>0.05) on the egg white index and haugh unit but significantly (P<0.05) on the egg yolk index. It can be concluded that adding a combination of black cumin flour (Nigella sativa) and noni leaf flour (Morinda citrifolia L) does not significantly affect the interior quality of quail eggs.

This study aimed to determine the performance of Simbal cattle pre-weaning. The research was conducted by a direct survey and measurement method sample cattle. Research variables include birth weight, weaning weight, average daily gain (ADG), body length, the height of the cattle’s hump, and chest circumference. Samples used were 30 Simbal cattle pre-weaning consisting of 15 males and 15 females. The data collected were analyzed descriptively, where the mean and standard deviation (x̄ ±Sd) were calculated. To determine the effect of sex, the data were then analyzed by T-test. The data analysis shows that average daily gain and weaning weight were significantly different (P<0,05) between males and females. The body size of cattle, including body length and hump height of male Simbal, was higher than females (P<0.05), while the chest circumference of male and female Simbal was not significantly different (P>0.05)

This study aims to determine the correlation of hatching weight with two-month-old body weight (final weight) of crossbreeds of a layer with kampung chickens based on four comb types.

Feed is a very important factor in cattle farming business. The adequacy of feed requirements is not only measured by the amount of feed given, but it is also necessary to pay attention to the diversity of types of feed and the ability of livestock to change the feed ingredients given to increase body weight. The research entitled Botanical Composition, Consumption and Feed Conversion for Male Bali Cattle in the Tunas Karya Group of Teruwai Village, Central Lombok Regency was carried out for 3 months from August to October 2021. This research was carried out using 3 Bali bulls which were placed in separate individual pens. equipped with feed and drinking water. Variables observed in this study included botanical composition, feed consumption, and conversion as well as body weight gain during the study. The data obtained in this study were analyzed descriptively. The results showed that the feed given to male Bali cattle reared in the Tunas Karya Group of Teruwai Village, Central Lombok Regency consisted of 100% king grass forage and 5 kg of commercial concentrate feed. Dry matter consumption (KBK) was 6.78 kg or 2.36% of body weight/head/day, while organic matter consumption (KBO) was 5.90 kg/head/day. Daily body weight gain (PBBH) was recorded at 0.526 kg/head/day, with a feed conversion of (12.1).

The purpose of this research was to determine the effect of the addition of egg yolk level in skim milk diluent on the motility and fertility of Pelung rooster spermatozoa. The study used a completely randomized design with 4 treatments. The treatments were P0: (skim milk + 0 % egg yolk)., P1: ( skim milk + 5% egg yolk)., P2 : ( skim milk + 10% egg yolk)., P3 : ( skim milk + 15% egg yolk). Analysis of variance results showed that the addition of egg yolk in skim milk had a highly significant effect (P<0.01) on the motility of Pelung rooster spermatozoa. The percentage of motility produced by P0, P1, P2, and P3 treatments is above 70% so it is still suitable for IB. The best treatment was P3 (skim milk + 15% egg yolk) on the motility of spermatozoa forming linear lines with the equation y = 0.61x + 76.74 and the coefficient of determination (R2) of 0.70. While Analysis of variance results showed that the level of egg yolk in skim milk diluent had a highly significant effect (P<0.01) on the spermatozoa fertility forming a quadratic line with the equation y=0.35x2 -0.64x + 6.10 and the coefficient of determination (R2=0.62). Fertility will be better without adding egg yolk. From the results of this research, it can be concluded that the addition of egg yolk level in skim milk diluent increases the motility, but not the fertility of Pelung rooster spermatozoa.

The study was conducted in a cattle breeding area between Bali and Simbal cattle in East Lombok Regency with the aim of determining the comparison of reproductive performance levels of Simbal and Bali cattle in smallholder breeding businesses. The variables observed included: an estrus postpartum, first artificial insemination after giving birth, service period, opening days open, and services per conception. Determination of the location was carried out by purposive sampling based on the population of cattle that are cared for. A sampling of cattle was done randomly with as many as 60 heads (30 heads of Bali cattle and 30 Simbal cattle). To determine the difference in reproductive efficiency between Bali and Simbal cattle, data analysis was carried out using a t-test. The results showed that the reproductive efficiency as measured by postpartum estrus, days open, service per conception, and calving interval was higher (P<0.05) in Simbal compared to Bali cattle, with an average value respectively 38.13 ± 5.4 days, 96.83 ± 8.15 days, 1.58 ± 0.58 times, and 323 ± 05 days for Bali cattle, while for Simbal the results were 83.34 ± 20.54 days, 163.04 ±16,34 days 2.50 ± 0.8 times, and 508 ± 43 days. Bali cows are very effective at producing calves every year, so their performance is more efficient than Simbal which has 185 days longer calving interval.

This study aims to obtain the right and efficient concentrate formula to produce maximum productivity of laying hens. The research method was action research at the location of layer farms by comparing the feed formula applied by farmers with the feed formula prepared as needed. The study used 21-week-old laying hens of the Lohman Brown breed with a total of 75 layers. The experimental design used was a one-way Randomized Complete Block Design with three different types of feed formulations, namely P1 (33.3% maize + 16.7% rice bran + 50% layer concentrate), P2 (36% maize + 26% rice bran + 38 % layer concentrate) and P3 (42% maize + 24.5% rice bran + 33.5% layer concentrate). The parameters observed were feed consumption, egg production per day, egg weight, FCR, and feed cost. Data were analyzed using Analysis of Variance (ANOVA) and Duncan's Multiple Range Test. The results showed that by reducing the concentrate level in the feed by 16% from what is usually applied by farmers, egg production, egg weight, and FCR were not significantly different (p>0.05), but the feed costs incurred were lower ranging from Rp. 68.02-84.12 per head per day. The conclusion of this study is that by optimizing the use of concentrates and feed prepared according to needs results in the same productivity but more efficient than the breeder's feed formula.
