“…The BWG of the lambs fed the NG diet was similar to those fed the CCs and PSs diets. These results agree with Santos et al [21] who found that BWG was affected by DMI. The high NDF and ADF contents (Table-1) in the agricultural by-product diets did not significantly decrease lamb productivity.…”

“…The carcass weights obtained in this study were similar to those reported by Setyaningrum et al [26], where Indonesian thin-tailed sheep weighing 17.5-18.8 kg produced 7.7-8.5 kg carcasses. Other studies reported that lamb carcass weights varied from 15.3 kg to 26.1 kg when originating from a slaughter weight of 34.3 kg-54.1 kg [21,[27][28][29][30]. Forwood et al [30] reported that heavier live weights produced higher carcass weights and dressing percentages.…”

Background and Aim: Grass is often scarce for ruminants during the dry season in Indonesia; thus agricultural by-products are widely used as a substitute for grass. This study aimed to determine the effect of replacing Napier grass (NG) with agricultural by-products on the productivity and carcass characteristics of lambs. Materials and Methods: Twenty-four 3-month-old male lambs with initial body weights of 13.26±1.29 kg (coefficient of variation=9.73%) were allocated into a completely randomized design with four treatments and six replications. The treatments included: NG=100% NG; corn cobs (CCs)=50% NG and 50% CCs; bagasse (BG)=50% NG and 50% BG; and peanut shells (PSs)=50% NG and 50% PSs. All treatment diets were pelleted and consisted of 40% fibrous feed and 60% concentrate feed, and contained 10.36-11.65% crude protein and 55.47-57.31% total digestible nutrients. Parameters observed included dry matter intake (DMI), dry matter digestibility, body weight gain (BWG), feed conversion ratio (FCR), feed cost per gain (FC/G), and carcass characteristics. Results: Lambs fed the PSs diet had the highest (p<0.05) DMI (781 g/d), digestibility, and body weight gain (92.5 g/d; p<0.05). The FCR of the PSs diet (9.13) was similar to NG. The FC/G of the PSs diet (IDR 23,541/kg) was the lowest of all diets. The BG diet had the lowest (p<0.05) digestibility, body weight gain (54.4 g/d), and the highest (13.53) FCR. No significant differences (p>0.05) were found in the carcass or meat characteristics of any diets. The averages of slaughter weight, carcass weight, and carcass percentage were 20.03 kg, 8.02 kg, and 40.0%, respectively. The average meat bone ratio was 3.67. Conclusion: It was concluded that agricultural wastes could be used as an alternative to NG at the level of 50% in the diet of lambs without a negative effect on production performance and carcass traits.

“…The influence of better nutrient density and quality of nutrient available for feed utilization and physiological state of animals on test diets might explain why animals on GK B , GK C and GK D were higher in total and daily weight gains than those on GK A . It has been evident that better feed quality diets with a possible increase in the digestibility provide better weight gain for animals (Santos et al, 2017). The observed trend in feed intake (Table 5) that decreased gradually with increased in Garcinia kola could be attributed to the palatability, physical and chemical forms of the diets.…”

Manipulation of the gut functions with feed additives has been recognized as an important strategy for improving performance and feed efficiency in goats. The purpose of the study was to determine the effect of Garcinia kola seed meal in diet supplements of goats; effect on rumen digestion, nutrient utilisation, blood metabolites and faecal flora. However, twenty-four West African dwarf male goats aged between 7 and 8 months old with mean live weight of 7.00 ± 0.38kg, were used in a completely randomized design for 84days. The goats were randomly allotted to four dietary treatments containing 0%, 2%, 4% and 6% of Garcinia kola inclusion levels. The 0% inclusion level served as the control group. Data obtained on rumen, metabolic and blood studies were analysed using one-way analysis of variance. Results obtained showed that rumen pH, total volatile fatty acids, ammonia nitrogen, acetate and propionate ratio, ether extract digestibility, nitrogen output, white blood cell, urea, cholesterol, feed intake and E. coli were significantly (P < 0.05) higher in GKA than other diets. Acetate, butyrate, neutral and acid detergent fiber were higher (P < 0.05) than diets GKA, GKC and GKD. Animals on GKC were significantly (P < 0.05) superior in propionate, digestibility of crude protein, fiber and its fractions, with nitrogen free extract, nitrogen retention, packed cell volume, haemoglobin, red blood cell, total protein, glucose and weight gains. Nitrogen intake and lactobacilli were significantly (P < 0.05) higher in animals on GKD. However, significant (P > 0.05) difference did not occur in rumen temperature, digestibility of dry matter with ash, albumin, globulin, creatinine, initial with final body weight, Enterobacteria, Coliforms bacteria and total bacteria load. It was concluded that goats fed diets containing 2% and 4%Garcinia kola inclusion levels had better rumen fermentation, nutrient utilisation, blood profile and faecal flora than those fed on 0% and 6% inclusion levels.

The purpose of this experiment was to formulate and evaluate milk replacer on the production performance of twin lambs from before weaning to one month after weaning. Three pairs of twin lambs aged two weeks with a body weight of 3.83 ± 0.4 kg were divided into two groups, each consisting of three lambs. The treatments applied were PSI = lamb given mother's milk and PMR = lamb given milk replacer. Pre-weaning dry matter consumption data were analyzed descriptively and other data were analyzed using the T-test. The results showed that the dry matter consumption lambs that were given milk replacers in pre-weaning was 164.18 ± 31.25 g/head/day with the largest proportion coming from milk replacers (61.4%). PSI group lambs had dry matter and energy consumption after weaning, daily gain before and after weaning, and body weight when weaned were significantly higher (P <0.05) than the PMR group lambs. However, the ratio of feed conversion and body weight at 90 days in the two groups of lamb were not significantly different. All lambs were healthy and no one died. It is concluded that formulated milk replacer provides production performance in lambs that are equivalent to lambs fed with mother's milk. ABSTRAKTujuan dari percobaan ini adalah untuk memformulasi dan mengevaluasi susu pengganti (milk replacer) terhadap kinerja produksi anak domba kembar dari sebelum disapih hingga satu bulan setelah disapih. Tiga pasang anak domba kembar berumur dua minggu dengan bobot badan 3,83± 0,4 kg dibagi menjadi dua kelompok yang masing-masing terdiri dari tiga ternak. Perlakuan yang diterapkan adalah PSI = anak domba yang diberi susu induk dan PMR = anak domba yang diberi milk replacer. Data konsumsi pakan pra sapih dianalisis secara deskriptif dan data yang lain dianalisis dengan menggunakan uji-T. Hasil penelitian menunjukkan bahwa konsumsi BK anak domba yang diberi milk replacer pada pra sapih adalah sebesar 164,18 ± 31,25 g/ekor/hari dengan proporsi terbesar berasal dari milk replacer (61,4%). Anak domba kelompok PSI memiliki konsumsi bahan kering dan energi setelah disapih, pertambahan bobot badan harian sebelum dan setelah disapih, dan bobot badan saat disapih nyata lebih tinggi (P<0,05) daripada anak domba kelompok PMR. Namun, rasio konversi pakan dan bobot badan umur 90 hari kedua kelompok anak domba tidak berbeda nyata. Semua anak domba sehat dan tidak ada kematian. Disimpulkan bahwa susu pengganti yang diformulasi memberikan kinerja produksi pada anak domba yang setara dengan anak domba yang diberi air susu induk.Kata kunci: susu pengganti, susu induk, kinerja produksi, anak domba kembar
