Live and Carcass Characteristics of Boer- and Savannah-Cross Kid Buckling Goats Fed Dried Distillers Grain with Solubles

The available supply of domestic goat meat has not matched the increased demand for goat meat. High cost of production is a concern of goat producers, with feed being a major factor in input expenses. Increasing slaughter weight of kid meat goats would increase the available goat meat, but requires added nutrition beyond that obtained from typical forage based systems for goat production. Savannah bucklings (n=31) and Boer bucklings (n=28) were stratified by weight and breed and were randomly assigned a treatment of 0 (T1), 15 (T2), 30 (T3), or 45 (T4) percent dried distillers grain with solubles (DDGS). One goat from each pen was harvested on day 0 (H1), and every 21 days (H2, H3, H4) so that equal numbers of goats from each breed were sacrificed each harvest time. Bucklings and feed refusal were weighed weekly. Data was analyzed for ANOVA using Proc Mixed for fixed effects of treatment, harvest time and breed. There were no significant interactions for any traits measured. Breed did not affect (P\u3e0.05) live performance, carcass traits, or cutability. Average daily gains (ADG) tended to linearly decrease with inclusion of DDGS, but significant difference were only observed in the second 21 days with T4 goats having the lowest (P\u3c0.05) ADG. Treatment had no effect on feed efficiency. Goats in H4 had the highest (P\u3c0.05) 1 and 3-hour temperatures and goats in H1 had the lowest (P\u3c0.05) 1 and 3-hour pH values. The H4 carcasses had the largest ribeye areas and heaviest weights for most primal cuts. Carcasses and most primal cut weights of T4 goats were lighter (P\u3c0.05) than those of goats in T1 and T2. Percentage of primal cuts in relation to the cold carcass did not differ (P\u3e0.05) for treatments, but were influenced by harvest time. Warner-Bratzler shear force did not differ (P\u3e0.05) for treatments and harvest time. The level and length of time feeding DDGS can affect goat carcass characteristics. This study found no differences in live traits, carcass characteristics, or meat from Boer- and Savannah-cross buckling kid goats

Carcass characteristics and meat quality of lambs fed high levels of spineless cactus in the diet

The objective was to evaluate the effect of increasing the dietary inclusion of spineless cactus (Nopalea cochenillifera Salm Dyck) on the carcass characteristics and meat quality of confined lambs. Thirty-two male Santa Inês lambs with an average age of 140 days and an initial body weight of 20.4 ± 2.60 kg were used in this study. The lambs were housed in individual stalls for 70 days and individually fed a ration with spineless cactus included at 0, 241, 519, or 753 g/kg of dry matter (DM). The lambs were slaughtered, and characteristics of the carcass and meat were recorded and analysed. Inclusion of spineless cactus had a quadratic effect on the bodyweight at slaughter and on the empty bodyweight of the lambs. The inclusion of 500 g/kg of spineless cactus provided the highest predicted cold carcass weight (16.03 kg). There was a quadratic effect of the inclusion of spineless cactus on the weight of meat cuts and leg composition of lambs. The inclusion of spineless cactus did not influence pH, tenderness, and water-retention capacity of the meat. However, the intramuscular fat content increased 1 mg for every 10 g/kg inclusion of spineless cactus in the diet. Quadratic effects were observed of the inclusion of spineless cactus on the weights of the liver, heart, rumen, blood, skin and internal fat of the lambs. Up to 500 g/kg of spineless cactus could be included in the diet of confined lambs

Effects of Nutritional Factors on Fat Content, Fatty Acid Composition, and Sensorial Properties of Meat and Milk from Domesticated Ruminants: An Overview

Simple Summary Nutritional interventions in ruminant livestock management is an essential step to achieving high quality meat and milk products for diversified and competitive global markets. The alterations of fat content, fatty acid profile, and the associated sensory properties of meat and milk have attracted much attention; they are accomplished with the managing of feeding systems and nutrition of ruminant diets. The literature has detailed various feed types and ingredients that facilitate the sustainable use of abundant, novel by-products, secondary products, non-conventional feedstuffs, or minimally processed biological materials within ruminant farming systems. Relevant to major feed ingredients is the knowledge of their macro- and micronutrients, as well as their bioactivity and functionality in meat and milk products. This review examines these and provides an overview of various concentrate feeds and forages that are fed to ruminants, and how they relate to the fat content and fatty acid profile of their meat and milk products. These insights will be valuable to those seeking to understand and adopt nutritional measures for the enhancement of domesticate ruminant meat and milk products.Abstract The meat and milk products from domesticated ruminants are important foods within a balanced diet, offering a rich source of energy, protein, fats, minerals, and vitamins. The sensorial properties of meat and milk are mainly linked to their fat content and fatty acid composition, which are influenced by the feeding background or nutrient composition of diets. While several studies have investigated the nutritional effects on the fat content and fatty acid profile of ruminant meat and milk, as well as their relationship with sensorial properties, a comprehensive overview of these effects is lacking. This paper summarises current literature and discusses changes to fatty acid composition (including omega-3 concentrations), fattiness, and associated quality traits of sheep, goat, beef cattle, alpaca, and llama meat that can be achieved by using different forages or feeds in a total mixed ration. Additionally, it presents the shelf life and nutritional value of meat, milk, and cheeses from the milk of dairy cattle, buffalo, goats, and sheep as influenced by a ruminant diet. Further advancement in these areas will promote the sustainability of ruminant production and its associated feeding systems in achieving premium quality animal-derived foods

An Analysis of Management Practices---Louisiana Sheep Producers Association, 1986.

The objectives of this study were: (1) To develop a personal profile of the membership of the Louisiana Sheep Producers Association (LSPA). (2) To determine the relationship between flock management practices followed by members of LSPA and their purpose for producing, size of operation, age and education. (3) To determine the educational needs in sheep production. The data were obtained by a mail questionnaire sent to 275 of the 304 members of LSPA. A total of 189 members engaged in sheep production returned the surveys. Chi-square, analysis of variance and correlation analysis was used to determine statistically significant relationships (.05 level of significance). Results showed the average LSPA member was 44 years old, had some college (55 percent), maintained 20 ewes, 1 ram, and 23 lambs, had 12 years of experience, devoted 17 acres to sheep, owned/operated a combination registered/commercial flock, felt club/feeder lamb production was his primary purpose, had a technical/manual occupation, felt fellow sheep producers were his best source of information, felt he needed information on flock health, and considered parasites, footrot and reproduction his major problems. Findings of this study parallel previous studies on adoption of agricultural practices. Specialized operations generally have high levels of adoption. Seedstock (purebred ram/ewe) producers adopted more practices followed by club/feeder and market lamb producers. Size of operation was directly related to level of adoption. The larger operations (over 30 ewes) adopted more management practices. Most agricultural practice-adoption studies have shown an inverse relationship between age and level of adoption (younger adopt more practices). This study differs in that older producers (51 and above) had the highest level of adoption. Adoption levels were very similar for the different levels of education in this study. Of the management practices surveyed, eight were adopted by over 80 percent, 27 by over 50 percent, while eleven were adopted by less than 50 percent of the LSPA members. Fellow sheep producers and magazines were primary sources of information. Flock health, nutrition and reproduction were areas of expressed concern. Results indicated four areas of low management levels: pasture and forages; genetics and reproduction; health; and marketing (wool)

Finishing lambs using an integral feed under a restricted-feeding program in an intensive production system in Northern Mexico

The objective of this study was to compare the productive performance of finishing lambs using an integral diet under a restricted-feeding program. Ten Dorper lambs were assigned to two homogenous groups according to live weight and age under a complete randomised block design. Group 1 was fed a traditional diet commonly used by the producer and group 2 was fed an integral feed restricted to 75% of dry matter requirement of lambs. The evaluated variables were: dry matter intake, initial and final live weight, daily weight gain, feed efficiency and body growth expressed in height, body length, thoracic diameter, cane length and cane width. A partial cost analysis was carried out to evaluate the economic viability. Lambs fed with the integral feed had better feed efficiency, higher dry matter intake, daily weight gain, height, body length and thoracic diameter when compared with the lambs fed the traditional diet. The use of an integral feed under a restricted-feeding program reduced the cost of finishing lambs by 2.46 dollars per head and finishing length by 120 days. Overall, providing an integral feed under a restricted-feeding program is a viable alternative for improving finishing lambs under intensive conditions in the Northern Mexico
