The once bred gilt system of production has a number of benefits in terms of feed efficiency and welfare, however the system relies on the production of a quality carcass and acceptable reproductive performance. Previous studies have indicated that welfare might be improved if gilts were ad-libitum fed a diet containing 60% Sugar beet pulp (Stewart et al 1993). There was a suggestion however that reproductive physiology may be put at risk using such a diet. The objective of this experiment was to identify differences in reproductive performance using two different energy sources in gestation and to manipulate nutrition during lactation to study the effect on carcass quality.

The Relationship

One of the problems that exist in the community is the lack of identification of the reproductive performance of prospective brooders of Bali cattle that are artificially inseminated. The researcher conducted a research to determine the reproductive performance of Bali Cattle inseminated with Brahman Cattle Semen in SECP (Special Effort for Cows to be Pregnant Program) Program in Kolaka Regency. The parameters observed in this study were; artificial insemination's first age (Years), How many times the artificial insemination (AI) was pregnant (S/C), Length of pregnancy (months), Calving Interval (CI) (months), Birth weight (Kilograms), Correlation of AI's first age with birth weight. Sources of date used in this study are primary and secondary data. Data collection techniques carried out in this study were observation and interviews. The date obtained was analyzed descriptively, analysis of variance, average, and to calculate the relationship between variables was analyzed by correlation. Reproductive performance of Bali Cattle inseminated with Brahman Cattle Semen in SECP Program in Kolaka district include; first age AI 23.63±1.99 months, Service per Conception (S/C) 1.56±0.55, gestational age 9.03±0.38 months, Calving Interval (CI) 12.24±0 .52 months, birth weight 27.85 ± 2.96 and the correlation between AI prime age and birth spacing was 0.77.

Sheep Production

In 1970 and 1971, the performance of ewes grazing oats at various stocking intensities during the final stages of pregnancy was compared with that of ewes, at stocking intensities considered optimal, on subterranean clover-annual grass pasture. Grazing oats produced no more winter feed than pasture in 1970, though quality of the oat herbage was better. In 1971, oats produced more, and better quality, herbage than pasture. Much greater ewe weight gains per head and per hectare were obtained on oats than on pasture in both years. In 1971, for example, ewes rotationally grazed on oats at 37 ha-1 gained 8 times more per head, and 23 times more per hectare, than ewes at 12 ha-1 on pasture. However, gains in reproductive performance and wool production were small or negligible.

Research Recommendations

This review of sow welfare addresses all aspects of housing for adult female pigs, including the issue of piglet welfare during lactation. It puts the issue of sow welfare in perspective by briefly outlining different approaches to the scientific assessment of welfare, the ‘feelings, preference, nature, and the functional or homeostasis’ approaches. We believe the last approach currently offers science the best assessment of welfare and is the approach that is utilised in this review. It involves comparing housing or husbandry systems and risks to welfare on the basis of relative changes in biological (behavioural and physiological) responses and corresponding decreases in fitness (growth rate, reproductive performance, or health/injury/immunology). The review discusses the following areas: (i) housing of individually housed pregnant pigs, with subsections on tethers, stalls, reproductive performance, exercise, and new stall designs; conventional, alternative, and outdoor group housing with subsections on aggression, electronic feeding stations, ecoshelters, and other alternative group housing designs; and other issues, such as lameness, culling, straw and other substrates, diet and hunger, quality of stockpeople, and housing around mating including oestrus detection and mating; and (ii) farrowing and lactating pigs with subsections on farrowing crates and alternative farrowing systems, stress around farrowing and during lactation, maternal behaviour and piglet survival, and sow and piglet injury and lameness. Conclusions and recommendations arising from the review include the need for public education to provide an informed consumer base that will result in some consensus on welfare issues among diverse interest groups and the need for industry education that results in better animal welfare and a sustainable industry. Some specific research recommendations include space allowance and the duration of housing for individually housed pigs, welfare issues of breeding sows in ecoshelters, piglet mortality in alternative systems, aggression in conventional and large groups, bedding, and hunger.

Female Cattle

Reproductive performance of female cattle is one of the important factors that need to be known in supporting the efficiency of beef cattle breeding programs so that the dam can produce calves every year. This study aimed to evaluate the potential and reproductive performance of female Bali cattle to preparing a baseline for cattle breeding production in SL-SPR Maju Bersama, Sungai Lilin District. Three hundred and thirty female Bali cattle owned by 247 farmers were measured and recorded based on their production and reproduction performance. Data were collected by interview and observation. Data were analyzed using statistical and descriptive methods. Reproductive performance obtained is the age first calving 1098±120 days; calving interval 457,25±8,75 days; days open 109,25±8,57 days and service per conception 5,46±0,42. The average female cattle have a BCS value of 3 (43%). The result showed that the breeding of Bali cattle at SL-SPR had sufficient potential, but it was necessary to improve performance. The basic data obtained can be used to start a breeding business to increase populations and improve the genetic quality of Bali cattle.
