Abstract

The aim of the presentexperiment was to evaluate the influence of I 500 TU injection of Pregnant Mare Serum Gonadotrophin (PMSG) at the mating program in the Fresian Holstein (FH) dairy cow on the performancesof milk production, quality, and production efficiency. The experimentwas performed at Banaran Village, Cepogo Subdistrict ofBoyolali District used twelve heifers and the-pregnant first parity cow of about 350-450 kg body weight. A split-plot experimental design with heifer (Pol and first parity (P1) as a main plot, and PMSG doses (T0 and T ,)as a sub plot. Thus the treatmentwere I) heifer with no PSMG injection (P0T0), 2) PMSG injected heifer (P0T,), 3) first parity cow with no PMSG injection, and4) PMSG injected first parity cow P,T,). Measurements were conducted on 90 days milk production, mass weight of milk, fat and lactose contents, and milk production efficiency. Results showed that average milk productions of not injected (804.67 l) and injected PMSG heifers ( 1,286.92 l) were significantly different (P<0.05). However, injection of PMSGdid not significantly (P>0.05) influenced average milk productions of first parity cows ( J.0491 versus 1,4832.52 J, for not injected and injected PMSG cow, respectively). Fat production of the not injected and injected PMSG heifers were 25.27 and 41.12 kg (P<0.05), while not injected and injected PMSG first parity cow produced 34. 19 and 47 .0 I kg of fat, respectively (P<0.05). Lactose production of not injected and injected PMSG heifers were 39.11 kg versus60.70 kg (P>0.05). Milk production efficiency of not injected and injected PMSG heifers were 11.13 and 18.45%, respectively (P<0.05). whereas, not injected and injected PMSG first parity cow were 14.75 and I 8.6 % (P>0.05). In general there were no significant differenton theeffectof PMSG injection on milk quality components (mass weight, fat and lactose contents). In conclusion, in the present experiment PMSG injection improved milk pro• duction and it efficiency, but did not improved milk quality.

Abstract

This study aims to determine the effect of supplementary feeding on the reproductive performance of beef cattle and calf birth weight. Additional feed is given to cows who are pregnant (8-9 months) and after giving birth for 3 months. Additional feed provided is a complete feed prepared from local feed ingredients. The objectives of this supplementary feeding are: maintaining the condition of the mother's body, maintaining normal embryo growth, and accelerating postpartum estrus, as has been done in Megal Village, Pamotan District, Rembang Regency. Provision of additional feed to old pregnant beef cattle (8-9 months) and after giving birth for 3 months in Megal Village, Pamotan District, Rembang Regency. The conclusion of this study is that the provision of additional feed 5 kg / head / day to old pregnant beef cattle and after giving birth for 3 months can reduce the weight loss of beef cattle broods when the availability of feed is limited, increase birth weight of calves and accelerate postpartum estrus. estrus for the first time after childbirth). Provision of additional feed to late pregnant beef cattle and after giving birth is highly recommended, especially in areas where the availability of feed fluctuates.Key words: supplementary feed, reproduction, beef cattle
