Factors influencing cow performance and intake
ABSTRACT FACTORS INFLUENCING COW PERFORMANCE AND INTAKE Two studies were conducted to determine how weaning system, residual feed intake (RFI), and residual average daily gain (RADG) affect cow performance and intake. In Study 1, a two-year study was conducted using Angus and Simmental X Angus …

Effects of herd mean and standard deviation on cow indexes for milk , and adjustments of cow indexes for these effects
Lactation records of cows born since 1964 were used to compute Cow Indexes (CI) for 581,519 Holsteins and 352,758 Jerseys. CI were used to predict Modified Contemporary Deviations (MCD) of daughters at three levels each of herd mean (µ) and standard deviation (σ), and regressions were compared to …

The microbial ecology of cow slurry in vermiculture beds
The suitability of cow slurry as a substrate for vermicomposting by Eisenia fetida was investigated. Particular attention was given to the effects of the earthworm on the decomposition and stabilisation of the slurry; and to the interactions between E. fetida and the microflora of the substrate. …

Lowering ruminally degradable protein in lacatating dairy cow diets
Lactating dairy cows convert 25 to 35% of intake N to milk N, and a part of the remaining N ends up in the environment, causing pollution. Dairy cows absorb amino acids available in the small intestine supplied mainly by digestion of microbial protein and ruminally undegraded feed protein (RUP). …

Effects of housing beef cow-calf pairs on dry lot vs pasture on cow performance as well calf performance and behavior through feedlot receiving
… were to analyze the effects of housing cow-calf pairs in dry lots (DL) or pasture (PAST) on cow performance and reproduction and calf performance and behavior through the receiving phase. Simmental × Angus (n = 108; 87 ± 11.5 d postpartum) spring-calving cows were stratified by age, BW, …

Financially Optimal Culling Strategies for Western Canadian Cow-Calf Producers
Canadian cow-calf producers often experience slim margins and focus on reducing costs to maximize their economic profit. This study aims to identify financially optimal breeding female culling strategies using production and financial data from 16 ‘typical farms’ in the Canadian Cow-Calf Cost of …

Studies on the Luteal Function in the Late Pregnant Cow
Corpora lutea (CL) from cows at 270 (5) or 250 (5) days of gestation were incubated with LH or cAMP. CL of cows at 250 days had increased progesterone accumulation in response to LH and cAMP while the group at 270 days did not respond to LH. Higher plasma concentrations of estrogens were found in …
