Thirteen suckling buffalo calves were divided into two groups according to their body weight, age and sex (T1Control (No LC. supplementation, T24 g LC. Per calf in breast milk). The Calves were fed 10% of their body weight fresh milk 2 times daily and provided calf starter and clover hay to meet their requirements of DM according to Kearl (1982). Calves body weight was recorded at the start of the experiment and thereafter regularly at 10 days interval. Diarrhea occurrence also faecal scores have been detected. After completion of the feeding trial, three animals per treatment were used in a metabolism trial. We obtained blood samples at the end of the study from each calf through jugular vein puncture. Obtained results showed significant (P< 0.5) increase in roughage, concentrate and total DM intakes with calves fed LC-supplemented than the control (T1) group during the periods of P3, P4 and P5. Supplementation of LC. L to calves in T2 group had showed an increase in body weight than T1group; the increase in total gain and average daily gain (ADG) was significant (P<0.05), CP, CF, EE and NFE digestion coefficients keep on the same trend. Diarrhea occurred on T1 calves were more than T2 calves, and the duration of diarrhea at the same time was longer in control calves than treated calves. The number of E.coli in feces was more in control calves than treated calves. Immunological parameters (IgA, IgG and interleukin 2) have been increased in treated calves than control with no significant difference (P>0.05).","PeriodicalId":355358,"journal":{"name":"Menoufia Journal of Animal Poultry and Fish Production","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125605290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"IMPROVING SHEEP PRODUCTIVITY BY USING FRESH AND FROZEN SEMEN IN PALESTINE","authors":"H. Bast, Omayma A. Khamis, E. Sabra, H.

The backbone of this sector is sheep and goats (small ruminants), dairy cattle and poultry. This study aimed to improve sheep productivity and develop long term breeding program for sheep breeds and crosses under field conditions in Palestine under different production systems. This experimental study included 169 ram sheep. The single semen collected from each ram was divided into four parts and extended using four extenders: milk, TRIS, TEST, and CJ-2 (diluted to 600 million sperm/ ml) and loaded into 0.25 ml straws for storage at 4 and 15° C. Most of the computer assisted sperm analyze the motility parameters were higher after extension and storage at 4 compared with 15°C (P < 0.05). Ram semen stored using milk or TRIS based extenders at 4° C. They are also retained similar sperm motility parameters but both were higher compared with TEST or CJ-2 extenders after storage for up to 3 days (P <0.05). Results showed that ram race AF recorded (151) with ratio 89.3 % while the race IA recorded (18) with ratio 10.7%. The entire169 ram from Ministry of Agriculture had pregnancy check after 41 days of semen insemination and the result was 100% pregnancy happened. Date of birth was after 5 months of semen insemination. On the other hand, average number of births was1.5. The greatest numbers of births (89) were belonged to females which represent 52.7% of the total births while the male births were 80 with ratio 47.3%. The net average weight of a newborn was about 5.6±1.4 kg. The weights of births were gradually increased and the average weight of a newborn at weaning was about 19.5±2.3 kg. The average amount of milk in the first stage of milking was about 1.7±0.29 L while in the second stage of milking was about 1.6±0.29 L and finally in the third stage of milking was about 1.46±0.28 L. In conclusion, the ram race AF recorded with higher ratio than the race IA. The average weight of a newborn at weaning was about 19.5±2.3 kg. Finally the third stage was reported to be with the least value of all the stages of milking.","PeriodicalId":355358,"journal":{"name":"Menoufia Journal of Animal Poultry and Fish Production","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123481717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
