Feed intake and growth performance of goats supplemented with soy waste

Abstract

-The objective of this work was to evaluate the effects of supplemental feeding of soy waste on the feed intake and growth rate of goats. Twenty male crossbred (Boer x local) goats were assigned to two isonitrogenous diet groups: one of commercial pellet and the other of soy waste. The commercial pellet (1.0%) and soy waste (0.8%) were provided on the dry matter basis of body weight (BW) per day, to the respective group of each diet. The soy waste group had lower daily intakes of total dry matter (0.79 vs. 0.88 kg) and organic matter (665.71 vs. 790.44 g) than the group fed pellet; however, the differences on daily intakes for grass (0.62 vs. 0.64 kg), crude protein (96.81 vs. 96.83 g), and neutral detergent fibre (483.70 vs. 499.86 g) were not significant. No differences were observed between groups for BW gain. The feed conversion ratio and feed cost per kilogram of BW gain were lower for the group fed soy waste than for the one fed pellet. Goats fed supplemental soy waste have a lower total dry matter intake, feed conversion ratio, and feed cost per kilogram of body weight gain than those fed commercial pellets.Index terms: Pennisetum purpureum, commercial pellet, crude protein, feed conversion ratio, neutral detergent fibre. Consumo de alimento e desempenho produtivo de cabras suplementadas com resíduos de sojaResumo -O objetivo deste trabalho foi avaliar os efeitos da alimentação suplementada com resíduos de soja sobre o consumo alimentar e a taxa de crescimento de cabras. Vinte machos de cabras cruzadas (Boer x local) foram designados a dois grupos de dieta isonitrogenada: um de pélete comercial e outro de resíduos de soja. O pélete comercial (1,0%) e os resíduos de soja (0,8%) foram fornecidos, com base na matéria seca da massa corporal por dia, ao grupo respectivo a cada dieta. O grupo da dieta com resíduos de soja apresentou menor consumo diário de massa de matéria seca total (0,79 vs. 0,88 kg) e de matéria orgânica (665,71 vs. 790,44 g) do que o grupo alimentado com pélete; no entanto, as diferenças de consumo diário de gramínea (0,62 vs. 0,64 kg), proteína bruta (96,81 vs. 96,83 g) e fibra em detergente neutro (483,70 vs. 499,86 g) não foram significativas. Não se observaram diferenças entre os grupos quanto ao ganho de massa corporal. A taxa de conversão alimentar e o custo do alimento por quilograma de ganho de massa corporal foram menores no grupo alimentado com resíduos de soja do que no alimentado com pélete. Cabras suplementadas com resíduo de soja apresentaram menores consumo total de matéria seca, conversão alimentar e custo da ração por quilograma de peso vivo do que as suplementadas com ração comercial.

“…Dried SR can also be used as a protein source in both terrestrial animals and fish feed because of its high protein content and relatively low price (Yang, 2005). There have recently been a number of studies evaluating SR as a protein source for raising ruminants (Harthan & Cherney, 2017;Rahman, Nakawaga, Abdullah, Emong, & Akashi, 2014), pigs (Hermann & Honeyman, 2004) and broilers (Sinha, Sinha, Mahto, & Ranjan, 2013). At the moment, very little information is available on the effects of SR in fish feeds (Sun et al, 2007;Wong & Tang, 1996).…”

Developing Sustainable Livestock Production by Feed Adequacy Map: A Case Study in Pasuruan, Indonesia.

“…Dry matter digestibility has become the main source of feed in various regions that have small natural feed production capability. The fruits and vegetables waste have important ingredients for livestock, such as phytochemicals (carotenids, phenolics, and flavonoids), antioxidants, antimicrobials, vitamins, or fats, which are enriched by an advance technological systems (Schieber, 2001;Fernández-López, 2008;Rahman et al, 2014;Saleemdeeb, 2017). Feed from organic waste materials has been traditionally used, and new technology can be used to convert it into a qual-The water recharge area in Pasuruan is located in Arjuna Mountain area consisting of Prigen, Purwosari, and Purwodadi covering 135.57 km 2 and recharge area in Bromo Mountain area covering Tutur, Tosari, Puspo, and Lumbang with total area of 312 km 2 .…”

“…Food crop waste support factor in Pasuruan a modern intensification (Thornton, 2010). There is a relationship between livestock and agricultural production, which supports the growth of densely populated livestock, or allows it to be intensively developed in agricultural areas (Bos et al, 2013;Pretty & Bharucha, 2014;Rahman, 2015). In contrast, degradation of agricultural areas will significantly reduce livestock populations and sustainability (Deshar, 2013;Tesfa & Mekuriaw, 2014;Sonneveld et al, 2016).…”

Okara as a protein supplement affects feed intake and milk composition of ewes and growth performance of lambs

“…High growth rate and efficiency decrease the time that it takes the lambs to reach market weight, which in turn decreases the labor and feed costs associated with raising lambs. There have recently been a number of studies evaluating okara as a protein feed for growing ruminants ( Rahman et al., 2014 ; Harjanti et al., 2012 ), but little is known about the effect of okara on lactating ruminants. Therefore, the objective of this study was to determine the effect of okara as a protein supplement on ewe feed intake, milk composition, and lamb growth.…”
