This investigation aimed to assess genetics of body conformation and feed efficiency traits in a control line of Rhode Island Red (RIR) chicken taking single hatched out pedigreed 100 chicks at Central Avian Research Institute, Izatnagar, India. Data was analyzed by least squares analysis of variance. Least squares means of chick weight (CW), body weight (BW), shank length (SL), keel length (KL...

This study evaluated the effects of gradual replacement barley with oats on enteric CH4 emissions, rumen fermentation, diet digestibility, milk production, and energy utilization in dairy cows fed a grass silage-based diet. Sixteen lactating Nordic Red received total mixed ration [58:42 forage:concentrate dry matter (DM) basis]. Grass silage (Phleum pratense) was sole forage canola meal (10% DM...

In total, 20 multiparous Holstein-Friesian dairy cows received one of four diets in each of four periods of 28-day duration in a Latin square design to test the hypothesis that the inclusion of lucerne in the ration of high-yielding dairy cows would improve animal performance and milk fatty acid (FA) composition. All dietary treatments contained 0.55 : 0.45 forage to concentrates (dry matter (D...

the effect of a commercial probiotic (protexin) on growth performance and survival rate in sobaity sparidentex hasta was investigated. 240 fish with average weight of 2.99±0.87g were treated for 10 weeks. this study was carried out in a completely random design with 12 experimental groups, in 4 treatments each with 3 replicates. experimental groups were consisted of four levels of 0.0, 0.5, 1.0...

background: excessive use of antibiotic growth promoters leaded in the creation of antibiotic-resistant bacteria and by consuming animal products, humans are at risk of receiving their residual. therefore, instead of using antibiotics as growth promoters, some alternatives must be identified and introduced to animal breeders. objectives: the purpose of this research was to study the effect of a...

Widyaratne, G. P. and Zijlstra, R. T. 2007. Nutritional value of wheat and corn distiller’s dried grain with solubles: Digestibility and digestible contents of energy, amino acids and phosphorus, nutrient excretion and growth performance of grower-finisher pigs. Can. J. Anim. Sci. 87: 103–114. Two experiments were conducted to evaluate the nutritional value of distiller’s dried grains with solu...

Effect of fibrolytic enzyme supplementation on nutrients utilization of sheep was studied. Twelve male Patanwadi sheep (12-15 month) were randomly divided in two groups of 6 each. Sheep were fed rations containing 50 % wheat straw and 50% compound concentrate mixture. A fibrolytic exogenous enzyme @ 0.025% was added to the ration of animal fed TMR. At the end of 14 weeks experimental period, an...

This experiment was conducted to evaluate the effect of vitamin C (L-ascorbic acid) and chromium (chromium picolinate, Cr Pic) on egg production, some egg characteristics, and digestibility of nutrients in laying hens (Hy-Line) reared under a low ambient temperature (6.2°C). Two hundred and ten laying hens (32 week-old) were divided into seven groups, 30 hens per group. The treatment groups wer...

ABSTRACT The objective was to evaluate the intake and digestibility of nutrients, ingestive behavior, performance goats fed with spineless cactus genotypes resistant carmine cochineal (Miúda or Orelha de Elefante Mexicana (OEM). Thirty castrated male goats, without defined breed, aged 12 14 months, an average body weight 19.0±2.8kg, were distributed in a completely randomized design among three...
