Effects; of Graded Levels of Dietary Lasalocid on Perlormance of llolstein Cows During Early Lactation

Six groups of Sahiwal-Friesian crossbred cows, namely M50-1, M50-2, M50-3, M56, M63 and M75-1 were evaluated. In total 180 cows were used and milk collected was evaluated for composition and quality. The effect of genotypes was significant (P≤0.05) only for titrable acidity (TA) and milk yield (MY). The M50-1 had the highest milk yield per day (8.73 ± 1.65 kg) but this was not significantly dif...

In a randomised controlled trial a lactation nurse assisted mothers during the early weeks after parturition both in hospital and at home. All mothers who started breast feeding were entered into the trial. The lactation nurse significantly extended duration in the study group compared with controls, particularly during the first four weeks and among women of lower social class.

Abstract This study was conducted to investigate the prevalence of subclinical mastitis and its contagious environmental bacterial causes in dairy cows Jos Metro polis Plateau State. A total 208 milk samples were collected aseptically from 52 lactating subjected California Mastitis Tests (CMT). Milk transferred into peptone water broth for enrichment, followed with bacteriological assays bioche...

Our study investigated the potential for important in vivo drug-nutrient transport interactions at the lactating mammary gland using the L-carnitine transporter substrates, cefepime and L-carnitine, as proof-of-concept. On d 4 (n = 6/treatment) and d 10 (n = 6/treatment) of lactation, rats were administered cefepime (250 mg/h) or saline by continuous i.v. infusion (4 h). Serum and milk L-carnit...

The pathogenicity of Streptococcus uberis and S. infrequens for cow udder was compared by experimental intramammary inoculation, mostly during the dry period. There were no significant differences between the two species according to the number and the length of infections at the subsequent lactation (Table 1). No infections could be established in lactation. The pathogenic and taxonomic implic...

The aim of this study was to characterize patterns of energy balance through lactation of cows kept under constant feeding conditions. Danish Holstein, Danish Red, and Jersey cows were studied during consecutive lactations and remained on the same dietary treatment throughout. They were fed a normal (13.55 MJ of digestible energy/kg of dry matter) or a lower energy diet (12.88 MJ of digestible ...

Omental adipose tissue lipoprotein lipase (LPL) activity, nucleic acid content and triglyceride fatty acid composition were estimated on 5 goats in late pregnancy and early lactation. These data were compared with animal production parameters, plasma metabolite contents and milk triglyceride fatty acid composition. Adipose tissue LPL activity and oleic acid content decreased whereas nucleic and...

Through maternal effects, information about environmental conditions experienced in the maternal generation can be transmitted to subsequent generations. Although maternal effects have been described and quantified in many mammalian species, the underlying causal links are often under-studied. The close association between mother and neonate during the extended period of lactation in mammals pr...
