this experiment was conducted to evaluate the effects of different levels of dried lemon pulp (dlp) on performance, carcass traits, blood biochemical and immunity parameters of broilers. in this experiment 240 of broilers (ross-308) were used in a completely randomized design with 4 treatments and 3 replicates (with 20 birds in each replicate) from 1 to 42 days. experimental diets included: 1) ...

A multi-trait selection index designed to improve the overall economic performance of hill sheep, including both maternal and lamb traits, has been developed and tested in a selection experiment over 7 years. Two versions of the index were tested, with different economic weights applied to the traits, on two different hill farms: one version including maternal and growth traits; the other versi...

ABSTRACT: The study evaluated the effect of sex and slaughter weight on carcass traits non-carcass components 1,489 horses (739 geldings 750 females, classified into eight groups according to their weight). Data were analyzed under a completely randomized design. Geldings had higher (P < 0.05) hot yield (HCY) cold (CCY) than females; however, fat yellowness values (b*) greater in females. Sl...

A trial was conducted to evaluate the effect of fat emulsifier on fat utilization in broiler chickens using 240 days old chicks which were divided into 24 replicates in a 3×2 factorial arrangement under Completely Randomized Design (CRD). Experimental diets were formulated using 1, 2 or 3% fat with or without fat emulsifier (Lecithin) at 350 mg kgG1. The trial lasted for 35 days and was divided...

this study was aimed to determine the effects of different dietary levels of methionine and protein on the growth performance and carcass characteristics of broiler chickens. a total of 240 broiler chicks were distributed into a completely randomized design with a 2 × 3 factorial arrangement. experimental factors were: two levels of protein (20% or 24% for starter and 18% or 22% for grower), an...

Heritabilities of and genetic correlations between additive direct and maternal genetic effects for calf market weight, and additive direct genetic effects for carcass traits, were estimated for Japanese Black cattle by REML procedures under 2-trait animal models. Data were collected from calf and carcass markets in Hyogo and Tottori prefectures and analyzed separately by prefecture. Calf marke...

This study aims to determine the use of boiled water jengkol (Archidendron pauciflorum) peel in drinking on broiler carcass performance. The used 96 DOC broilers type MB 202 PLATINUM with a duration 4 weeks. research method is an experimental using completely randomized design (CRD) 6 treatments, namely P0: Control (Drinking without waste), P1: 2% (2ml decoction/100ml water), P2: % (4 ml peel/1...

Weaned British x continental crossbred steers (n = 108, 7 to 8 mo of age) of medium or large frame were used in a replicated experiment with a 2 x 4 factorial arrangement of treatments over 2 yr. Management regimens consisted of backgrounding for 150 d and finishing for 0, 30, 60, and 90 d. Carcass data were collected, and samples from the longissimus muscle were analyzed for long-chain fatty a...
