| Abstract | ||||
| The present study aimed to investigate the effects of parity, type of Dirth and kid’s sex on milk yield an:i kids growth of Zaraibi goats. The effects on body physiological reactions and some blood constituents have been also nvestigated. Thirty-six adult Zaraibi does (12 first parity, 12 second parity and 2 third parity), immediately, after kidding were used throughout the 17 Neeks of lactation period. Weekly milk yield determination was performed by kid suckling technique. Blood samples were taken on day 1, 3 and 5 after •idding, then weekly (blood samples were collected) from cade doe. Blood samples were analyzed for packed cell volume (PCV), haemoglobine (Hb), serum total protein (TP), albumin (AL), total lipids (TL), glucose, cholesterol, lamic oxaloacetic transaminase (GOT) and glutamic pyruvic tcansamiflaSe tGPT). Bi-weekly pulse and respiration rats as well as rectal temperature re recorded. The results showed,that mi’k yield increased as the number of arities increased. Does bearing male and triplet kids produced more milk than those bearing female and single or twin kids. At the first week after birth, third parity kids were heavier than those of the first and second ones. Male kids and single born kids were heavier and grow faster than females and twin and triplet kids. The third parity does were more physiologically stressed than oes in their first and second parities. Changes in glucose, AL, GL, AL:GL ratio, TP, GOT, GPT:GOT ratio, TL and cholesterol were affected by parities, while Hb, GPT were not affected. The effect of the third parity was clear on the milk yield, kids weight, pulse rate, respiration rate, rectal temperature and ieamatological parameters, than those of the first or second parity. Goats have served mankind earlier and longer than cattle and sheep. It ¡s managed for the production of meat, milk and hair particularly in arid, semitropical or mountainous countries (Haenlein and Delaware, 1992). One of the w&l-knowri native Egyptian breed ¡s zaraibi goats, called Egyptian Nubian. Effective utilization of genetic variability of such breed of goat requires reliable and systematic information about genetic and non-genetic effects on their production characteristics. Previous investigations revealed, that a wide environmental and non-environmental factors affect the productive and reproductive performance of goats. Various investigators observed significant differences in body weight traits of kids due to their age of dams, sex and year and season of birth. Mekkawy (2000) observed that body weight of zaraibi kids increased with age of dam, but this increase was | ||||
