The present study was designed to investigate the effect of mastitis on various components including fat percentage, protein, total solids, solid not fat, pH, specific gravity and lactose content in milk cross-bred (Holstein Friesian × Cholistani) Sahiwal cattle. A 376 samples (excluding blind nonfunctional teats) from 100 cows (50 50 sahiwal) were collected aseptically. Animals different ages,...

BACKGROUND: Methionine has been suggested as the firstlimitingamino acid for milk production in ruminants. It is importanthow to increase milk protein yield and milk fat in dairy ruminants.OBJECTIVES: This study was set to investigate the effect of rumenprotected methionine (RPMet) on milk composition of lactatingCashmere Rayeni goats. METHODS: 40 healthy singletonCashmere Rayeni goats about 3 ...

This study compared the composition, yield, and freezing point of buffalo colostrum milk collected on 30th, 60th, 90th day lactation from purebred Murrah its crosses with Philippine Carabao. A total 133 samples were 36 buffaloes (20 16 “Murrah x Carabao” crosses) evaluated for fat, protein, lactose content, solids non-fat (SNF), solids, point. Colostrum contained significantly (p<0.05) more ...

The study was conducted to find the association of -Lactoglobulin locus with the milk performance traits in 157 lactating Sahiwal cows maintained at Cattle yard, NDRI, Karnal. Two different variants of -Lactoglobulin were detected from DNA by PCR-RFLP. It was found that the frequency of B allele was predominantly high (0.84± 0.03) than that of A allele (0.16± 0.03) in the population studied. ...

108 milk samples were collected to study the relationship of somatic cell counts (SCC) and milk composition with milking methods and udder hygiene from 27 Holstein Frisian (HF) dairy cows having moderate milk yield in mid-lactation and parity of 2 to 4, at Khyber Pakhtunkhwa Agricultural University Peshawar dairy farm. All animals were randomly distributed into three categories on the basis of ...

Fractions of herd-year-season, sire by herd interaction, additive genetic and dominance genetic variances were estimated for milk production traits in Holsteins of Japan using Method R. Inbreeding depressions for milk production traits were also estimated. Estimated fractions of herd-year-season variances ranged from 0.056 to 0.074 for yield traits and from 0.033 to 0.035 for content traits. Es...

Abstract This study investigated the effects of dietary supplementation with chestnut tannins (CNT) on metabolic and antioxidant status prepartum cows along their colostrum quality. Pregnant multiparous Holstein were paired according to parity body condition score, assigned either a diet supplemented 20 g/d commercially available product containing (CNT, n=20) or an unsupplemented control (CON,...

The raw milk quality has increasing importance for producer and consumer as it is directly related to processing, production and price. The aim of present study was to determine the relationship among intramammary infection (IMI) and raw milk parameters in Jersey crossbred cows. Total 24 lactating Jersey crossbred cows were randomly selected and representative animal wise morning milk samples w...
