Milk production was measured at 28-d intervals by the calf weight change method in 30 dams with twins and in 28 dams with single calves. Average adjusted 170-d weaning weights for twins were between 41 and 38 kg less than for singles (depending on linear contrast). Yet dams with twins weaned between 91 and 97 kg more calf and produced substantially more milk. Significant dam breed and parity di...

(co) variance components and genetic parameters for growth traits in arman sheep were estimated, using data collected during an 11-year period (1999-2010), by applying the restricted maximum likelihood (reml) procedure under univariate and bivariate animal models. the studied traits were body weight of lamb at birth (bw), body weight at 3 months of age as weaning weight (ww), body weight at 6 m...

Wastewater treatment (WWT) of wet flue gas desulfurization (WFGD) effluent, mercury and selenium control are becoming critical issues for many utilities operating with coal-fired power generation. Research has shown that absorber slurry oxidation reduction potential (ORP) is a primary factor for determination of control of WFGD chemistry. Previously unexplained swings in the ORP of operating WF...

Data from about 2900 litters (approximately 40,000 piglets) originating from 1063 Czech Large White hyperprolific sows were analyzed. The phenotypic and genetic relations between litter size traits, piglet mortality during farrowing and from birth to weaning and several statistics referring to the distribution of the birth weight within litter were analyzed. All genetic parameters were estimate...

ABSTRACT: This study measured milk and solid feed intake in pre- weaning period postweaning of Nellore calves, to correlated them with performance traits ingestive behavior animals classified as most least efficient. During pre phase, efficiency was evaluated 51 cow-calf pairs from 21±5 days after calving until weaning. post-weaning only male calves (n=23) were evaluated. Pre-weaning estimated ...

This study aimed to evaluate Brahman Cross cow from Indonesia Australia Commercial Cattle Breeding (IACCB) program through the Body Condition Score (BCS), calf birth weight, and weaning weight of at people farm “Koperasi Produksi Ternak (KPT) Maju Sejahtera” in Tanjungsari District, South Lampung Regency. was conducted March 2020 using survey method with census data collection which all 5 years...

Estimates of covariance components were obtained for milk production of beef cows, measured by the weigh-suckle-weigh method, and weaning weight and preweaning growth of their calves for a herd of Polled Herefords and a herd of a multibreed synthetics, so-called Wokalups. Analyses were carried out by restricted maximum likelihood fitting an animal model incorporating both direct and maternal ge...
