The aim of this study was to evaluate the influence weaning and concentrate supplementation on characteristics carcass cuts longissimus muscle Suffolk lambs finished a Tifton 85 (Cynodon spp.) pasture. Weaning strategies were evaluated in four finishing systems: i) non-weaned non-supplemented lambs; ii) supplemented with creep feeding; iii) weaned iv) concentrate. In systems weaning, at 46 ± 6 ...

Direct additive and maternal genetic effects on birth and weaning weight of Chios lambs were investigated. The data originated from the Agricultural Research Station of Chalkidiki and comprised 7318 lambs, raised over the period from 1977 to 1992. Variance components were estimated using restricted maximum likelihood, fitting six different animal models, by 2 including or excluding maternal eff...

I. The reproductive performance of rats reared from weaning on a moderately proteindeficient (LP) diet containing Sogcaseinjkg, or on a control diet (HP) containing 250 g casein/kg has been studied. Although the rate of growth was reduced in LP animals, these rats eventually achieved the same adult weight and appearance as the controls. 2. Weight gain during the first z weeks of gestation was s...

The current research aimed to determine Bali cattle's productivity in Bumirestu, Akedaga, and Dakaino Villages East Halmahera Regency. This was carried out Villages, Regency, for three months, from February April 2018. A presurvey field survey methods were applied observe several variables: calf weaning, mothers mating after calving, estrus age first calving age, body weight. Livestock could be...

In beef cattle farming, growth and carcass traits are important for genetic breeding programs. Molecular markers can be used to assist selection and increase genetic gain. The ADIPOQ, OLR1 and PPARGC1A genes are involved in lipid synthesis and fat accumulation in adipose tissue. The objective of this study was to identify polymorphisms in these genes and to assess the association with growth an...

Reproductive traits from 7642 ewes were recorded from 1975 to 1983. The ewes were of five breeds (Dorset (D), Finnsheep (F), Rambouillet (R), Suffolk (S) and Targhee (T)) and two composite lines [C1 (1=2F þ 1=4R þ 1=4D) and C2 (1=2F þ 1=4S þ 1=4T)]. Genetic parameters were estimated for six basic and seven composite traits. The basic traits were conception rate (CR), total number of lamb born (...

the aim of this study was identification of important factors and their effects on mortality of lori-bakhtiari lambs from birth to weaning. the data set used for statistical analysis were collected from 4991 lambs born between 1370 and 1384 in flock at lori-bakhtiari sheep breeding station. data was modeled using logistic regression. mortality variable as dependent and ewe weight at mating, ewe...

Thirty-seven pigs were used to evaluate the effects of age and weaning on the level of protease in the gastric mucosa and trypsin, chymotrypsin, amylase and lipase in the pancreas. There was a positive allometry of the pancreas and gastric mucosa associated with age and with weaning to a solid diet. Increases with age in total activity of chymotrypsin, trypsin, amylase and gastric proteases wer...

Ewe productivity is a composite and maternal trait that considered the most important economic in sheep meat production. The objective of this study was application alternative genome-wide association (GWAS) approaches followed by gene set enrichment analysis (GSEA) on ewes’ genome to identify genes affecting pregnancy outcomes lamb growth after parturition Iranian Baluchi sheep. Three traits a...
