Quantitative trait loci for bone traits segregating independently of those for growth in an F-2 broiler X layer cross [PDF]

, 2007
An F broiler-layer cross was phenotyped for 18 skeletal traits at 6, 7 and 9 weeks of age and genotyped with 120 microsatellite markers. Interval mapping identified 61 suggestive and significant QTL on 16 of the 25 linkage groups for 16 traits.

The Impacts of Shatamuli, Ashwagandha and their Combination on Growth Performance, Faecal Microbial Population and Blood Parameters in Sonali Chickens

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
ABSTRACT Background Phytogenic feed additives have shown potential in enhancing nutrient utilization, improving performance and mitigating pathogenic challenges in Sonali chicken. Objective The goal of the current study was to assess how Shatamuli (Asparagus racemosus) and Ashwagandha (Withania somnifera) affected the Sonali chickens' growth ...

Animal breeding in organic farming:Discussion paper [PDF]

, 2001
It is uncertain whether animals which have been bred for conventional production are capable of optimum performance in organic conditions. In conventional agriculture there is a movement towards maximum control of production conditions in order to ...

Purchase and production optimization in a meat processing plant

International Transactions in Operational Research, Volume 33, Issue 2, Page 1016-1051, March 2026.
Abstract This paper addresses an optimization problem concerning the purchase and subsequent material processing in a meat processing company. Unlike the majority of existing papers, we do not concentrate on how this problem concerns supply chain management, but we focus on the production stage, primarily the meat cutting.

Flexible Housing for Broiler Breeders , ,

Poultry Science, 1986
Abstract Broiler breeder performance in a conventional curtain sidewall house and a flexible (FLEX) house from 27 to 64 weeks was compared in two separate trials. Trial 1 was initiated in June of 1982 and Trial 2 in October of 1983. The conventional house was equipped with thermostatically controlled curtains and a stirring (Casablanca type) fan. The

Genetic Parameter Estimation for Pregnancy Loss and Their Association With Reproductive and Growth Traits in Brahman Cattle Under Extensive Tropical Conditions

Journal of Animal Breeding and Genetics, Volume 143, Issue 2, Page 365-374, March 2026.
ABSTRACT This study estimated genetic parameters for pregnancy loss (PL) in Brahman cattle and evaluated the genetic correlation of PL with growth and reproductive traits using both the pedigree relationship matrix (A) and pedigree plus genomic relationship matrix (H). Data were collected from two herds in Bolivia, focusing on three age groups: heifers,

Identification of novel candidate genes for follicle selection in the broiler breeder ovary [PDF]

, 2012
BACKGROUND: Broiler breeders fed ad libitum are characterised by multiple ovulation, which leads to poor shell quality and egg production. Multiple ovulation is controlled by food restriction in commercial flocks.

Quantitative Genetic Variation and Response for Harvest Body Weight in a Selection Program for Red Tilapia (Oreochromis spp.)

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT Genetic variation is indispensable for both natural and artificial selection, as well as evolution, adaptation, and the long‐term success of selective breeding programs. This study attempted to scrutinise genetic variations and responses within the breeding population of red tilapia across eight generations of selection (2016–2023).
