This study was conducted to investigate the effects of rumen-protected γ-aminobutyric acid (GABA) on feed intake, growth performance and expression of related genes in growing lambs. A total of 24 lambs weaned at age of 50 days were divided into four block of six based on their BW, six lambs within a block were allocated to three pairs, which were then assigned randomly to three treatments with...

the objective of this study was to evaluate whether the adverse effects of high dietary rice bran (rb) inclusion levels on the feed intake, performance, bone status and nitrogen (n) retention of broilers could be mitigated by wet feeding. giving a completely randomized design experiment in 2 × 2 factorial arrangement, seventy two broiler chickens, managed in 24 floor pens received one of the tw...

The objective of this work was to evaluate the nutritional parameters of young bulls supplemented with different ratios of protein: carbohydrate on tropical pastures from 4 until 18 months old. Fifty-five non-castrated beef calves (138.3±3.4 kg, 90 to 150 d of age) were used. The calves (young bulls) were subjected to a 430-d experimental period encompassing 4 seasons. The treatments were as fo...

this experiment was carried out for a determination of metabolizable energy and the effect of the grind multienzyme on in-vitro dry matter and protein digestibility in diets, and as well on performance of broiler chicks. a number of 800 day old unsexed arbor acres broilers were placed in 8 treatments and 4 replicates (25 chicks each). a completely randomized design (crd) of a factorial arrangem...

the present study was conducted on efficiency of utilization of dietary energy for milk production in lactating crossbred cattle. 18 lactating crossbred cattle of early to mid-lactation, approximate body weight (375.39±23.43 kg), milk yield, parity and stage of lactation were divided into three groups of six animals each and were fed 0, 50 and 100% diammonium phosphate (dap) in the mineral mixt...

in order to investigate effects of partial replacement of starch with neutral detergent soluble fiber (ndsf) on weekly weight gain, feed intake, feed conversion ratio, digestibility and some histopathological changes of rumen, 16 lambs were used in completely randomized design. the experimental period was 70 days. dietary treatments were 1- control (high starch), 2- beet pulp, 18 percent, 3- be...

this study was performed to evaluate the effects of crud protein (cp) level on dry matter intake in prepartum period, productive performance and health of fresh cows. twenty multiparous holstein cows were assigned randomly to one of two dietary treatments. dietary treatments were treatment 1, 13% cp of dm (control), and treatment 2, 16% cp of dm. diets were similar in lactation net energy and r...

fifteen holstein male calves (416 ± 35 kg initial bw; mean ± sd) were employed in a replicated 3 × 3 latin square test to investigate the effect of partial replacement of barley grain by wheat factory sewage (wfs) within three 22-d periods including 16 d of adaptation and 6 d of data collection. the basal diet (wfs0) consisted of 42.5% (dm basis) barley grain, partially replaced with either 23....

the study was conducted to compare the effects of feeding acacia auriculata (aa), gmelina arborea (ga), albizia lebbeck (al) and butryospermum parkii (bp) tree forages as a sole feed for nigerian goats. four goats (yankasa) averaging one year and weighing 11.7±1.8 kg were used to measure the feed intake, digestibility and nitrogen balance. the leaves were offered ad libitum. dry matter (dm) int...
