Biological evaluation of animal and vegetable protein test feeds in broilers and rats

Study was conducted to know the biological value of fish meal, meat meal, blood meal, sesame oil meal, cottonseed meal, and guar meal (Cyamopsis tetragonoloba) in two different species (ten day old broiler chicks, n=96; and weaning albino rats, n=64). These protein sources were added into nitrogen free diet on protein equivalent basis to formulate eight different diets including six test diets, a basal and a standard diet. Results revealed that both chicks and rats showed significant differences (p<0.05) in feed intake, weight gain and feed conversion ratio for animal and protein feeds. Fish meal in most of the measurements was similar (p>0.05) to casein in chicks. Weight gain ranked in declining order for diets containing fish meal, meat meal, sesame oil meal, cotton seed meal, blood meal and guar meal in both species. On standard stock diet ad libitum after drastic restriction period, both species showed a compensatory growth and nitrogen retention

Prevalence of Paramphistomum cervi in different sheep breeds of Balochistan (Pakistan)

The prevalence of Paramphistomum cervi infestation in Balochi, Babrik and Harnai sheep breeds from Balochistan (Pakistan) was studied during September to December 2010. For this purpose, rumen of slaughtered sheep in Quetta City and surroundings (n=1,200) were examined. Results showed significant differences (

Influence of genetic and environmental factors on lactation http://www.openveterinaryjournal.com F.R. Al-Samarai et al

ABSTRACT Data on 100 Holstein-Friesian cows for a period of 15 years (1988-2002) were analyzed using least squares and maximum likelihood methods. Lactation components such as lactation length, peak yield, milk yield and age at calving averaged 319±56, 474±42 liters, 3661±785 liters, 1963±636 days respectively. The h 2 estimates were 0.49, 0.29, 0.32 and 0.535 for these parameters, respectively. Seasonal analysis revealed that there was no influence of calving season on lactation components. Summer, Autumn, Winter and Spring had lactation length 323±50, 317±49, 313±56 and 321±55 days, monthly peak yield 477±77, 472±70, 466±53 and 482±73 kg, and milk yield 3685±766, 3593±817, 3645±677, 3724±864 kg., respectively

NUTRIENTS INTAKE AND DIGESTIBILITY OF LOHI LAMBS AND BEETAL KIDS FED UNDER INTENSIVE MANAGEMENT SYSTEM

ABSTRACT Study was conducted to compare the performance of sheep and goats under confined situation. Sixty animals (lambs n=30, 10 month of age weighing 19.5 kg and kids n=30 of 10month of age weighing 11.5 kg) were selected and divided equally in four groups, 2 each for lambs and kids.Both species were offered fodder ad libitum with concentrate supplement 240 grams/animal/day and total mixed ration ad libitum. Results showed that DM, CP, NDF, ADF intakeswere significantly (P˂0.05) better in lambs than kids. Dry matter and crude protein digestibility was significantly (P˂0.05)higher in kids than lambs fed on total mixed ration and it was not different among both species fed on fodder plus concentrate supplementation.NDF, ADF digestibility wasmaximum (P˂0.05) in lambs than kids fed on total mixed ration. It was concluded that nutrients digestibility was better in kids than lambsfed on total mixed ration. Similar pattern of digestibility was observed in both species fed on fodder plus concentrate supplementation
