OBJECTIVE This study investigated the effect of fermented biogas residue (FBR) of wheat on the performance, serum biochemical parameters, and meat quality in pigs. METHODS We selected 128 pigs (the mean initial body weight was 40.24±3.08 kg) and randomly allocated them to 4 groups (1 control group and 3 treatment groups) with 4 replicates per group and 8 pigs per pen in a randomized complete ...

This experiment was conducted to evaluate the effects of dietary levels of crude protein, methionine and betaine on performance and carcass characteristics of broiler chickens. A total of 640 one-day-old broiler chicks from Ross 308 strain were used. Each pen (1.5 ×1.5m) was assumed as experimental unit and was included 20 male and female chicks. The experiment was conducted based on completely...

effects of partial docking on feedlot performance and body fat characteristics were studied in a fat-tailed sheep breed. thirty-eight male lambs with an average weight of 4.44 ± 0.48 were randomly divided into two groups. the lambs in one group were partially docked at 3-4 h after birth, using rubber rings, and the lambs in another group remained intact (control). after weaning, 20 male lambs f...

An investigation was conducted to evaluate the management effect of feeding triticale on the performance of crossbred feedlot cattle. Steers were weighed at fortnightly intervals until 83 days. Steers were weighed at 0700hr and fed upon (7 animals/treatment) at weighing on d 0, 20, 40, and 83 of the trial. Measurements were made of daily feed intake, average daily gain, body weight gain and fee...

SUMMARY Two trials involving 216 growing boars were conducted to study the effects of different levels of crude protein on daily gains, feed efficiency, feed intake and estimated carcass characteristics. The boars were fed either a 16, 18 or 20% crude protein ration from 23.8 to 55.8 kg (period 1). Upon completion of period 1, the protein level was reduced 2% for each treatment (14, 16 and 18%,...

The objective of this study was to examine if diets differing in crude protein (CP) metabolizable energy (ME) ratio (CP:ME) pre-weaning altered peripheral quantitative computed tomography (pQCT) measures bone mass and strength lambs. left hind leg lambs were available at the completion a trial designed effect that altering CP:ME milk replacer had on growth body composition pre-weaned reared art...

Net feed conversion efficiency (NFCE) describes whether an animal eats more or less feed than expected for its size and growth rate. Early results from the Trangie NFCE Project, and from the Beef CRC, show that considerable variation in NFCE exists within each of the British breeds tested and is moderately heritable. Estimates of heritability for average daily gain, 365-day weight, feed intake,...
