The objectives of the current experiment were to study the response of the growth performance of early finishing gilts to different net energy (NE) concentrations in diets, and to compare the NE values of diets between calculated NE values and measured NE values using French and Dutch CVB (Centraal Veevoederbureau; Central Bureau for Livestock Feeding) NE systems. In a metabolism trail, the NE ...

in order to investigate the effect of diets contained urea and molasses on fattening performance and blood urea nitrogen (bun) density of male lambs, 72 arabic male lambs were used in a completely randomized design with a 3×4 factorial experiment, for 90 days. the experimental diets contained; 0, 0.5, 1 and 1.5% of urea each with 0, 7.5 and 15% of molasses, in isoprotein and isocalaric diets. t...

Heifer rearing is one of the largest production expenses for dairy cattle operations, which is one reason milking operations outsource heifer rearing to custom developers. The cost of harvested feedstuffs is a major expense in heifer rearing. A possible way to lower feed costs is to graze dairy heifers, but little research exists on this topic in the mid-south United States. The objectives of t...

The study was conducted at Pig farm of AICRP on Pigs, Livestock farm, Adhartal, College of Veterinary Science & A.H., Jabalpur (M.P.) for a period of three months. A total of 36 Large White Yorkshire crosses (LWY X Desi) were randomly assigned to six different groups and diets were formulated as per ICAR (1998) standard. All the diets were isoproteinous except group-6, which was formulated as p...

In the past several years, consumer demand has forced the swine industry to select for an animal with increased percent lean and higher lean accretion rates. Paylean is a technology that has been shown to increase carcass leanness while improving growth performance when fed to finishing pigs. It has been documented that average daily gain (ADG) and feed efficiency (F:G) are improved when feedin...

Abstract In this research communication we describe the performance of dairy cow−calf pairs in two cow-driven CCC-systems differing cows' access to calves through computer-controlled gates (smart gates, SG). We investigated machine milk yield automatic milking system (AMS), calf growth, and intake supplemental concentrate. Two groups each with four cow-calf were housed a cow area, creep meeting...

Background: Selection based on traits such as average daily gain (ADG) and carcass quality in commercial pig populations have drawn attention of swine breeders due to the correlation with growth consumer preference for composition, respectively. The association between melanocortin 4 receptor (MC4R) gene, which encodes G-protein-coupled ADG quality, been well documented. study was conducted det...

AIM This study was planned to investigate the effect of feeding different levels of chayote (Sechium edule) meal by replacing standard concentrate mixture (CM) on the growth parameters such as feed intake, body weight gain, average daily gain (ADG) and feed conversion ratio (FCR), and nutrient utilization in indigenous pig of Mizoram. MATERIALS AND METHODS Twenty-four growing indigenous pigs ...

ABSTRACT: Growth hormone (GH), insulin-like growth factor 1 (IGF1), and leptin (LEP) can be candidate genes for association studies because they play vital roles in the metabolism process. Thus, this study aimed to identify variants these associated with body traits Santa Ines sheep. The following were recorded: weight at 100 (BW100) 240 days (BW240), average daily gain (ADG), withers (WH) crou...

Addition of L-lysine (Lys), L-tryptophan (Trp) and(or 55 ppm carbadox (C) to low protein corn-soybean meal diets was evaluated in two experiments using 444 crossbred pigs. In Exp. 1, initial and final weights of pigs were 17.7 and 33.3 kg, respectively, for the 28 d experiment. Pigs fed the 13% protein diet containing added Lys (.17%) or Lys + C had average daily gains (ADG) similar to those fe...
