There is a paucity of data on the beef production potential of Norwegian Red (NOR) compared with 'modern' Holstein-Friesian (HF) cattle. The present study used a total of 64 bulls in a 2 × 2 factorial design study encompassing two breeds (HF and NOR) and two slaughter ages (485; E, and 610; L, days). The mean initial age and live weight of the HF bulls were 179 (s.d. 47.1) days and 203 (s.d. 64...

AIM The objective of the study was to evaluate the effect of deep litter housing and fermented feed on carcass characteristics and meat quality of crossbred Hampshire pigs. MATERIALS AND METHODS Forty-eight weaned crossbred Hampshire piglets of 2 months age (24 males and 24 females) were selected for the experiment. The piglets were randomly assigned into 4 homogenous experimental groups with...

In genetic improvement programmes for beef cattle, the effect of selecting for a given trait or index on other economically important traits, or their predictors, must be quantified to ensure no deleterious consequential effects go unnoticed. The objective was to compare live animal measurements, carcass composition and plasma hormone and metabolite concentrations of male progeny of sires selec...

The objective of this study was to estimate genetic parameters for the weights of different wholesale cuts, using an experimental and a commercial data set. The experimental and commercial data sets included 413 and 635 crossbred Belgian Blue, Charolais, Limousin, Angus, Holstein, and Simmental animals, respectively. Univariate analyses using a mixed linear animal model with relationships were ...

The present study was performed to investigate the effects of dietary electrolyte balance and probiotic on the performance and carcass characteristics in Japanese quail under heat stress conditions. A total of 672 quail chicks (20-day old) were studied in a three-factor, factorial experiment with 4 replicates and in each replication of 14 birds during 20 to 37 and 20 to 41 days Factors included...

The study was conducted on estimation of eviscerated carcass weight using live weight as predictor for Arsi Bale sheep and goat of both the sexes, reared under farmer’s management and on natural pasture. The age group of the studied sheep and goat were <1 year (category 1) and >1 but < 2 years (category 2). The age of the animals were estimated by dentition method. The results indicated that th...

Study was carried out to find out the effect of L-carnitine supplementation on carcass characteristics in Venncobb broiler chicks fed with diet containing animal fat. Eighty day old commercial broiler chicks were randomly allotted to two treatment groups (T1 and T2) with four replicates of ten chicks each. The birds were fed with standard broiler chicken ration (BIS, 1992) containing 5% animal ...

the present research was conducted to estimate the dietary lysine (lys) requirements of growing quails as based on performance and carcass constituents parameters at 3 to 24 d of age. the experiment was carried out in a complete randomized design arrangement the 6 dietary lys levels; 1, 1.15, 1.30 (nrc 1994), 1.45, 1.60, and 1.75 %, from 3 to 24 d of age. a dose-response diet mainly based on co...

Live animal and carcass data were collected from market barrows and gilts (n = 120) slaughtered at a regional commercial slaughter facility to develop and test prediction equations to estimate carcass composition from live animal and carcass ultrasonic measurements. Data from 60 animals were used to develop these equations. Best results were obtained in predicting weight and percentage of bonel...

The current study was conducted to investigate the effects of genetic and non-genetic factors on body weight and carcass traits of Japanese quails. Two strains of Japanese quail (150 wild quails and 150 white quails) were used as base population. Four mating groups were used to produce progenies: wild male × wild female, white male × wild female, wild male × white female and white male × white ...
