“…This similar DMI indicated positive response of sheep on the dietary brewer residue without refusal. This is also following the general theory that small ruminants could adapt to diets due to their regulatory mechanism to adjust their nutrient need (Hayati et al, 2021;Ribeiro et al, 2021).…”

Industrial brewing companies produce a high quantity of solid residue rich in nutrient contents that can be utilized as a feed ingredient for fattening sheep.This study aimed to evaluate the optimal proportion between rice bran and brewer residue in Indonesian local sheep. The study was designed as a completely randomized block design with a basal diet consisted of 60% forage and 40% concentrate. In total, 15 male sheep were randomly allocated to receive one of three dietary treatments with five replicates in each (P1 = 70% rice bran + 30% brewer residue; P2 = 50% rice bran + 50% brewer residue; and P3 = 30% rice bran + 70% brewer residue). The parameters observed included nutrient intake, body weight gain, rumen microbial protein synthesis, and NH 3 concentration. The results showed that brewer residue did not affect nutrient intakes, average daily gain (ADG), rumen pH, and microbial protein synthesis. However, replacing rice bran with 50% and 70% (inclusion rate of 19% and 29% in the diets, respectively) of brewer residue increased dry matter digestibility and NH 3 concentration in the rumen. To conclude, brewer residue can be used up to 29% to replace 70% rice bran used in the diets of Indonesian male local sheep without negatively affected sheep's performance.

“…Visual observation based on vulvar redness, wet swelling, and mucus discharge was helpful for the detection of estrous signs (Hayati et al, 2021). The thin, transparent, and watery mucus discharge from the vulva is a signal to the estrus dairy cows (Lim et al, 2014;Bernardi et al, 2016) and Egyptian Baladi cows (Damarany, 2020).…”

“…According to Baliarti et al (2018), signs of estrus in some cows were incomplete due to the influence of maintenance, especially at the level of farmers who raised cows with minimal feed. Adequacy of crude protein was very important for the expression of estrus signs for optimizing reproductive performance (Hayati et al, 2021).…”

Accurate determination of estrus status in an animal based on an appropriate estrus detection method can guarantee the cows' pregnancy after mating. This study aims to determine the estrus status of Aceh cows using the van Eerdenburg estrus behavior scoring method. This study was conducted from 22 January to 12 February 2021, at the Technical Implementation Unit for Animals of the Faculty of Veterinary Medicine, Universitas Syiah Kuala, Banda Aceh, Indonesia. The sample used was eleven Aceh cows aged 4-6 years old. Parameters observed were the number of cows exhibiting signs of estrus using the estrus behavior scoring method. The accuracy of estrus detection was confirmed by palpation per rectum to detect the presence of uterine tone. By observing signs of estrus using the method studied, 90.9% (10/11) of the cows were determined to be in estrus. Confirmation by the presence of uterine tone showed a 100% accuracy rate. The most effective sign of estrus was the passivity of the cow when being ridden by another cow or bull. This study concluded that estrus status in local cows could be determined using the estrus behavior scoring of the van Eerdenburg method.

This study aimed to evaluate the effect of mixed feed sorghum-Indigofera on Garut ewes reproductive performance stimulated with Pregnant Mare Serum Gonadotropin (PMSG) hormone. Twenty-eight multiparous Garut ewes were grouped based on feed type (local forage (LF) vs. mixed feed sorghum-Indigofera (SI)), for a 30-day acclimatization period with a completely randomized design. Following acclimatization, all animals were synchronized with PGF2α (i.m.) twice, 11 days apart. Half the population of each group was stimulated with 500 IU PMSG after the second injection. Estrous characteristics were observed for seven days, followed by natural mating. Pregnancy status and the number of fetuses were detected 30 days after mating using ultrasound (USG), and reproductive efficiency was evaluated after parturition. Data during acclimatization were analyzed using a two-sample t-test, while the reproductive performances used a General Linear Model (GLM). Estrous characteristics showed no interaction (p>0.05) between feed types and PMSG stimulation. The onset of estrous in the SI treatment occurred 9.33 hours faster (p<0.05) than in the LF treatment. Meanwhile, the duration of estrous in the group stimulated with PMSG was 18.67 hours longer (p<0.05) than without PMSG. The vulva temperature at standing heat was 38.16±0.69 °C (p>0.05), with the pregnancy rate ranging 42.85%-100%. Interestingly, the SI group treated with or without PMSG had a larger litter size (1.43-4.50) compared to the LF group (1.25-1.33). It is concluded that feeding with SI had improved reproductive success, with the highest number of ewes giving birth. Additionally, the ewes fed SI with PMSG had the largest litter size.
