“…Accordingly, in the present study, body weight and its changes were sharply decreased to -3.6, -3.4, -2.5 and -2.2 kg for G1, G2, G3 and G4, respectively after kidding then gradually decreased up to 45 day of lactation and began to increase later that may be related to the stress of lactation and milk production (Table 8). These findings are in close agreement with those recorded by Kalbande and Thomas (1999) who also reported that higher levels of protected protein (2% tannins) reduced line weight loss in lactating jersey cows. It means that addition of protected protein plus Ch-F into the ration of goats in their early lactation phase could be alleviate the effect of negative energy balance that almost appeared in this critical period.…”

This study aimed to investigate the effect of treated sunflower meal with 2% condensed tannins (Quebracho tannins, QT; Unitan, Argentina) or/and Chamomile Flowers supplementation on productive performance of Zaraibi dairy goats and their offspring. A feeding trial was conducted using twenty pregnant goats at the 3 rd and 4 th parities and initial body weight 35.55 ± 0.62 kg at the last month before parturition and lasted for 90 days after parturition. Animals were divided into four similar groups (n=5does/each) using the randomized complete block design. Goats were fed concentrate feed mixture (CFM) to cover 50% of their requirements according to NRC (1985) for goats and rice straw (RS) was given by 150 g/head/day; while berseem was given at ad-libitum. Group G1 (control) received CFM contained untreated sunflower meal, while group G2 fed CFM contained untreated sunflower meal and supplemented with 0.25% Chamomile Flowers (Ch-F) and G3 fed CFM contained treated sunflower meal with 2% tannin (Quebracho) and G4 fed CFM contained treated sunflower meal with 2% tannin (Quebracho) and supplemented with 0.25% (Ch-F) on DM basis. Results indicated that digestibility of most nutrients and feeding values were significantly higher (P<0.05) with G2 than those of other groups. While, digestibility of CP was significantly higher (P<0.05) for all tested groups than that of control one. Ruminal ammonia-N and total volatile fatty acids concentrations were lower significantly (P<0.05) in G3 and G4 than G1 and G2. Daily milk yield was significantly (P<0.05) higher with G4 over the whole experimental period than that of control and insignificant higher than the other tested rations. Meantime, the improvement in 4% fat corrected milk yield being 124, 110 and 103% for G4, G3 and G2 compared to that of G1 over the whole experimental period. Milk constituent contents did not significantly affected by dietary treatments despite there were slightly increases in milk constituents with G4 ration in comparison with the other treatments. Also, feed conversion as kg DMI, TDNI or DCPI per kg milk improved for G4 in comparison of other groups. Economic efficiency of G4 recorded the best one among the experimental treatments and increased by 21.18% based on control ration (G1). Also, G4 revealed significant (P<0.05) positive effect on final weight, total and daily weight gains for kids during suckling period. No deleterious effects on liver, kidney functions and general health of animals fed the manipulated rations. It could be concluded that the protection process of sunflower meal with 2% QT and supplemented with 0.25% Chamomile Flower (G4) was more beneficially effective on Zaraibi dairy goats performance and economic efficiency.

“…However, data from 21 studies on cattle and 19 studies on buffaloes were subsequently excluded, because the information in these reports was incomplete with respect to one or more of the essential variables such as body weight, milk yield, milk fat percentage, weight change and nutrient intake. Thus data from 14 studies11–24 on buffaloes and 25 studies25–49 on cattle were used in the present study. These studies were conducted across a wide range of locations and conditions in India.…”

An attempt was made to assess the comparative dry matter intake and nutrient utilisation efficiency of lactating buffaloes and cows based on results obtained from experimental feeding trials conducted in India. Data on dry matter (DM) intake, total digestible nutrient (TDN) intake, digestible crude protein (DCP) intake, body weight or metabolic body size (MBS), body weight change, milk yield or 4% fat-corrected milk (FCM) yield, milk fat percentage and roughage/concentrate ratio in the diet of lactating buffaloes and cows were collected from published reports. The data were processed and analysed to assess the comparative dry matter intake and nutrient utilisation efficiency using suitable statistical analysis models. DM intake was significantly (P < 0.01) lower in buffaloes (2.57 kg DM per 100 kg body weight or 119.2 g kg À1 MBS) than in cattle (3.09 kg DM per 100 kg body weight or 132.0 g kg À1 MBS). Mean gross energetic efficiency (30.53 versus 27.83%; P < 0.01), gross protein efficiency (45.48 versus 37.06%; P < 0.01), net energetic efficiency (69.16 versus 64.10%; P < 0.05) and net protein efficiency (80.15 versus 59.59%; P < 0.001) were significantly higher in buffaloes than in cattle. Lactating buffaloes consumed significantly less (P < 0.001) protein (75.69 g DCP) and less (P < 0.01) energy (695.9 g TDN) than cows (93.89 g DCP, 774.8 g TDN) for production of 1 kg of 4% fat-corrected milk. Buffaloes had higher energy and protein utilisation efficiencies as compared with cattle at similar fat-corrected milk production level, plane of energy and protein nutrition, body size and body weight change. Buffaloes (1.189 kg DM kg À1 4% FCM) consumed a similar (P > 0.05) amount of feed dry matter to that of cows (1.267 kg DM kg À1 4% FCM). However, when DM intake kg À1 FCM (4%) was compared at constant levels of metabolic body size, fat-corrected milk, body weight change, dietary energy concentration and green forage percentage in the diet, lactating buffaloes consumed significantly less DM kg À1 FCM yield as compared with cattle. It was concluded that DM intake was lower in lactating buffaloes. Moreover, lactating buffaloes utilised dietary dry matter, energy and protein for milk production more efficiently than cattle.

“…Aktivitas mikroba yang meningkat akan menyebabkan penggunaan N-ammonia dan VFA meningkat pula, sehingga terjadi penurunan konsentrasi ammonia dan VFA. Kalbande dan Thomas (2001) [23] menyatakan bahwa ammonia akan digunakan oleh mikroba rumen untuk dikonversi menjadi protein mikroba dan VFA digunakan sebagai sumber energi dalam melakukan sintesis asam amino atau protein mikroba tersebut.…”

Penelitian dilakukan untuk mengetahui pengaruh pemberian Aspergillus niger iradiasi sinar gamma dosis rendah pada jerami padi fermentasi dan potensinya sebagai pakan ternak ruminansia secara in vitro. Proses fermentasi dilakukan dengan teknik Solid State Fermentation (SSF) menggunakan A. niger yang diiradiasi sinar gamma dosis rendah untuk meningkatkan kemampuan memecah ikatan selulosa. Orientasi dosis iradiasi sinar gamma sebesar 0, 125, 250, 375, 500, 625 dan 750 Gy dilakukan pada A. niger untuk mengetahui kondisi yang optimum dalam menghasilkan aktivitas enzim selulase. A. niger iradiasi sinar gamma pada dosis yang optimum digunakan untuk pembuatan jerami padi fermentasi dan dilakukan evaluasi kemampuan jerami padi fermentasi sebagai pakan ternak ruminansia secara in vitro. Perlakuan jerami padi fermentasi yaitu P0. Jerami Padi, P1. Jerami padi fermentasi A. niger 0 Gy dan P2. Jerami padi fermentasi A. niger 500 Gy. Hasil menunjukkan bahwa dosis optimum iradiasi sinar gamma pada A. niger dalam menghasilkan enzim selulase (3,24 U/ml) adalah 500 Gy. Pada jerami padi fermentasi A. niger 500 Gy menunjukkan aktivitas enzim selulase tertinggi yaitu sebesar 48,5384 U/g bahan kering (BK) dan kadar glukosa sebesar 247,33 mg/g BK pada hari ke-14. Proses fermentasi dengan A. niger iradiasi sinar gamma (500 Gy) mampu meningkatkan kandungan proein kasar, acid detergent fiber (ADF), neutral detergent fiber (NDF) dan bahan kering, namun menurunkan kandungan lemak kasar dan bahan organik (BO). Hasil fermentasi dalam cairan rumen dari jerami padi fermentasi dengan dengan A. niger iradiasi sinar gamma (500 Gy) menunjukkan nilai pH sebesar 7,01; konsentrasi ammonia dan volatile fatty acid (VFA) masing-masing sebesar 3,92% dan 4,73 mmol/100.
